Do-it-yourself roof rack: we make it ourselves and correctly attach car roof rails and racks (85 photos + video)

Trunk lock VAZ 2107

The luggage compartment lock of the VAZ 2107 has a simple design and fails extremely rarely, but sometimes it may be necessary to adjust or replace the mechanism.

Trunk lock malfunctions

Malfunctions of the trunk lock on Zhiguli cars of the seventh model are usually associated with malfunctions of the cylinder. In this case, the lock will need to be removed from the trunk lid and disassembled to replace the part. As for the adjustment, it is carried out when the luggage compartment lid does not close well or knocks while driving.

The trunk lock of the VAZ 2107 consists of the following parts: 1 - rotor axis; 2 — housing cover; 3 — drive extension; 4 — lever; 5 - spring; 6 - rotor; 7 — body; 8 — clamp; 9 — retainer plate

Trunk lock repair

To carry out repair work on the trunk lock, you will need to prepare the following list:

• wrench 10;
• installation;
• pencil;
• new lock or cylinder;
• Litol lubricant.

How to remove

To remove the luggage compartment lock, perform the following procedure:

1. Mark the position of the lock on the lid with a pencil.
2. Using a 10mm wrench, unscrew the 2 nuts securing the lock.
3. Disconnect the mechanism and remove it from the car.
4. By pushing the larvae inside the lid, it is dismantled.
5. Remove the cylinder together with the spacer bushing.
6. If necessary, remove the seal from the lock.

Replacing the larva

If the need for dismantling is due to replacing the cylinder, then before installing a new part, the mechanism is cleaned and lubricated with Litol. If the lock is completely replaced, the new parts of the product are also lubricated.

How to put

After lubricating the lock, it is installed in the following sequence:

1. Insert the sealing element into the luggage compartment lid.
2. Place the lock cylinder in the spacer sleeve.
3. Mount the cylinder together with the bushing into the lock.
4. Install the lock on the trunk lid in accordance with the previously made marks.
5. Fasten and tighten the mechanism with two nuts.

How to adjust the trunk lock

If the trunk lid lock on the “seven” closes with difficulty, it needs to be adjusted relative to the locking element. To do this, loosen the fasteners and change the position of the mechanism so that the latch easily fits into the body and the lever secures it well, and there is an equal gap between the luggage compartment lid and the body over the entire area.

Adjusting the trunk lid

Sometimes it becomes necessary to adjust the trunk lid. It happens that the part is located above the rear wings or is shifted to the right or left. If the trunk lid can be moved to the sides by unscrewing the fastening nuts on the hinges, then with an incorrect height position the situation is somewhat different.

The trunk lid is adjusted using hinged mounting nuts.

To adjust the lid in height, you will need to open it completely and, holding the edge of the lid with one hand, apply force in the hinge area with the other. A similar procedure should be repeated on the other side.

If the trunk lid is not positioned correctly relative to the rear wings, the hinges must be slightly bent

The main thing is not to overdo it. Then close the lid and check the tightness of its fit. If necessary, repeat the procedure. To adjust the force of opening the trunk lid, the edges of the torsion bars of the springs are shifted to one of the teeth of the luggage compartment hinges.

Opening the trunk with a button

I sanded it with coarse sandpaper and filled it with two-component automotive putty, then sanded it again.

Installed the trunk door activator. And again, not like people. The first thing I did was remove the lock cylinder, and with it the rod inside the door. Consequently, space became available. That's where the activator went.

I reliably insulated all the connections, wrapped all the wires in madeline, and also glued it along the perimeter of the casing, at the point where the casing comes into contact with the metal. I glued a small piece of 10x20 cm visa mat inside the door, on a flat area under the number.

I sealed the trunk trim with bitoplast.

I bought a waterproof button on the radio market, I was still in the military.

I cut it into the license plate light trim, from below.

Soldered it and filled it with sealant.

I connected an additional relay to the security system. To the wire that connects ground when disarmed, and disconnects in security mode. Those. disarm the system, the relay supplies +12 to the trunk button, press the button and the activator is activated. Accordingly, after arming, the relay opens, and when the button is pressed, the activator does not operate. Standing near the car, the button is not visible.

Visible only if you sit down.

Pressing the button is very convenient. Since we first apply force by pressing the button, and then the same energy is used to lift the trunk lid. As they say, with a slight movement of the hand.

Thresholds

The main purpose of the thresholds is to protect the vulnerable sides of the car body. For this reason, thresholds are often susceptible to damage. In addition, when getting in or out of the car, passengers and the driver periodically come into contact with them, scratching the elements with their shoes. As a result, the paintwork comes off from them, which causes corrosion and rotting.

On the “seven”, the classic replacement or repair of a threshold begins with adjusting the door hinges. If this is not done, then it will not be possible to replace the threshold correctly due to the gap.

After this, the following is done:

• The doors are removable;
• The threshold is cut off (first the outer part, then the amplifier);

The new amplifier is welded through the holes on it, as in the photo below;

A new threshold is set.

The price for a set of thresholds for VAZ 2107 starts from 200 rubles. The thickness is usually 2-3 mm.

The remaining body parts of the VAZ 2107, such as doors and trunk lid, also have a significant place in the design of the body and its geometry.

Each of the body elements of the “seven” has its own ID number, casting pattern and thickness. So, for the roof - 0.9 mm, and for the rear wheel arches - 1 mm.

Connecting the product

Before carrying out connection work, be sure to disconnect the negative terminal from the battery. To begin with, we present the diagram according to which the product will function.

The electric lock will be supplied with 12V power directly from the battery, although you can also use a wire from the cigarette lighter. First, connect the wire to the “+” terminal of the battery.

The battery supplies power to the relay, which can be located both in the cabin and in the engine compartment, which will be much more rational. From terminal “86” the wire is fed to the trunk opening button, which can be located in any convenient place on the dashboard. To install the button that will open the trunk lid, you will need to drill a hole of the appropriate diameter in the dashboard.

The wire from the relay terminal “30” is laid through the cabin to the activator. Its length must be at least 5 meters. The wire can be laid together with the standard wiring. This wire must be connected to the green wire of the activator using female-male connectors. The blue wire must be short-circuited to vehicle ground. Now you can check how the electric trunk lock of the VAZ 2107 functions. It is enough to spend 2-3 hours so that the trunk will eventually open using the VAZ 2107 button. After completing the work, do not forget to connect the negative terminal to the battery.

Kit selection

Installation will not be possible if you do not have at your disposal a set of equipment necessary for installation. Buying it is not difficult, but you need to think about which specific option is best for you.

In total, 2 solutions to the current situation are being considered. Namely.

Safety kit

Category: Light trailers

• Factory set. Purchased from trusted and reputable manufacturers. The kit contains almost everything you need, so you don’t have to assemble different elements. But the price is naturally higher;
• Amateur kit. Here we are talking about independently preparing all the necessary components. The motorist is faced with the question of where exactly to get them and how to choose a set so that everything fits. It is difficult to do this without relevant experience and certain knowledge. But you can save a lot of money financially.

I don’t know what exactly you will choose, but I want to give one piece of advice. Buy an electric drive equipped with an inertia mechanism. This will allow you to turn off the drive when an obstacle appears in the path of the luggage compartment lid. Roughly speaking, the drive will not pinch your hand or head when you poke around in the trunk.

So the inertial mechanism is a very useful thing.

If we talk about assembling a homemade kit, then it is important to collect several basic elements. These include:

• power window module 2 pieces;
• 2 mechanisms for lifting glass;
• wires;
• diodes;
• electromagnetic relay;
• five-pin relays;
• four-pin relays;
• Relay connection block;
• springs for the lid lock;
• power tools;
• wiring;
• nuts, bolts;
• Bulgarian, etc.

As you can see, the set is quite impressive. Therefore, consider whether it is worth trying to assemble the kit yourself. Sometimes it is much easier and even more economical to purchase a ready-made factory kit with a guarantee and all the associated benefits. Price does not always play a key role.

Subtleties of choice

When choosing a trunk, carefully study the types and information about the load capacity. If the trailer has a spring suspension of any design, which facilitates maneuvers over bumps and holes, then in the case of a roof rack on a car, with a shock-absorbing suspension of the car, it is separated by that very roof. It does not have pronounced properties to level out vibrations and take on the vector impacts of the load mass. But a body with inter-window pillars is a damper between the road and an additional high center of gravity. Therefore, they attach the trunk as low as possible to the roof, even one centimeter is important.

Trunk design

The golden rule: if the car has a pair of roof rails, then the corresponding cross members are selected. The dimensions must correspond to the distance between the rails

This is critical for even distribution where most of the weight is on key fasteners

If there are no elements, a set of fasteners is used to establish a connection between the trunk and the top of the car. The components of a basic trunk are few:

• Longitudinal arcs.
• Cross bars.

Support struts, which consist of:

• Brackets.
• Corners.
• Plastic platforms.
• Bolts, nuts and washers.

In practice, car racks come in different forms. The material used and the mechanical properties of the fasteners, together with the performance of the vehicle’s roof, determine the design and future purpose of the device.

Easy luggage rack selection

When purchasing a roof rack for your car, you should check:

• Vehicle make.
• Roof and body type.
• Year of manufacture of the car.

These parameters will help you avoid mistakes when purchasing. Subtleties follow

It is important to know what the roof rack supports and roof mounting rods are made of. They are made of steel and aluminum

When using the trunk for a short period of time, they stop with steel fasteners. With prolonged use, they become unusable and worsen their aerodynamic properties.

Advantages of aluminum racks:

• Anti-corrosion coating. With it, the service life increases significantly, therefore, the car owner saves money.
• Improved aerodynamics. The lower the air resistance, the more fuel the car saves.
• The aluminum basket is lighter. Installation and dismantling occurs quickly.
• An important parameter is the size of the structure. It is better to use a car trunk with adjustments.

Trunk mounting methods

Let's look at ways to attach a car rack to the roof:

• Full-time. When purchasing a car, the luggage rack fasteners are already included. And the mounting holes are hidden behind the door seal. This option is convenient and allows you not to waste energy searching for the necessary equipment. To ensure that the racks hold tightly, the set uses special bolts.
• Universal. Also called door. Installed using universal fasteners, fixed in the area of ​​​​the body's counter-relief, which follows the bend of the door. This option is expensive to install and takes time. Only a specialist can select the exact model of a universal trunk.
• Use of roof rails. A large number of vehicles have roof rails. These are devices that run parallel along the roof on both sides, made of plastic or metal. With their help, even installing a car rack yourself is much easier. Sometimes roof rails are equipped with mounting points to facilitate the installation process.

Important points

Even after the above information, the economical driver will say: “So what? A special trunk is expensive, the box is small, and an expeditionary one is certainly not needed. I will assemble from different sets.” Today there are all luggage racks with all the components, but if such a car owner manages to assemble the suitable parts separately, after the fifth time, he will pass on his experience to his colleagues in the garage:

• Crossbars and roof rails are selected by measuring the roof.
• Simple supports are made of cheap plastic. Therefore, they are susceptible to destruction, since they cannot tolerate both heat and cold.
• It is more practical to use stands made of aluminum, steel or ABS plastic. They will last much longer without losing their properties.
• The larger the volume of the trunk, the more things it can hold.

It’s convenient to have a large trunk and not think about how much space is left in it, but:

• You will have to pay extra for the volume.
• Increased fuel consumption.
• The design will have deteriorated aerodynamic properties.

Any model has a permissible load. When purchased, an incorrectly selected car rack will lead to deterioration in vehicle control and rapid wear of the structure. The roof of the car also has a permissible load capacity.

How to install a power lock on the tailgate

Before installation, you should prepare a set of necessary tools and additional materials. So, we will need:

1. Connecting wires.
2. Terminals.
3. Insulating tape.
4. Safety fastenings.
5. Set of wrenches.
6. Several screwdrivers (flat and figured).
7. Wire cutters.
8. Pliers.

To begin self-installation of the electric trunk lid drive, you must dismantle the plastic lining located on its inner side, which blocks access to the lock. Almost always, when purchasing this device, sellers offer to additionally purchase a lock that has already been modified for it. You should not ignore this offer, since purchasing it will allow you to avoid a number of trivial problems when installing the entire mechanism and will additionally save a lot of time and nerves. The next stage of installation will be laying the wiring to the lock from the cigarette lighter power supply. The choice of a cigarette lighter is justified if this element is almost never used. In addition, if necessary, the device can withstand increased loads. In order to power the electric lock, it is necessary to disassemble the cigarette lighter input to install a fuse between it and the drive start button.

The drive button can be installed in any convenient location. After this, we move on to laying the power wires along the thresholds of the car. This will require about 3.5 meters of cable. The final stage of installation will be the installation of a modified trunk lock, followed by its connection to the network and configuration

When connecting the electric drive, it is important not to reverse the polarity, otherwise the armature of the electric motor will rotate in the opposite direction, as a result of which the mechanism will not function. It would also be advisable to install a fuse in the circuit directly in front of the electric motor in order to avoid its possible failure

How to get to the salon

Gaining access to the interior of a VAZ-2107 will not be difficult, since additional security systems are usually not installed on this car. To gain access to the interior, you can use wire or fishing line. Let's look at each option in detail:

1. In the VAZ-2107, standard buttons with a larger diameter “cap” are installed on the doors. They are the ones who can help get rid of the problem of a locked door. Find a fishing line or thin rope that is long enough that you can make a loop in it and still have about 1.5 meters left. The loop should be in the center of the fishing line so that you can tighten it by the loose ends. There is a small gap in the upper left corner of the door through which you can push the fishing line inside the cabin. If it is too small, then take a wooden wedge and widen the opening. Next, all you need is sleight of hand - you need to hook the bolt by the upper part with a loop, tighten the fishing line, after which all you have to do is pull up to lift it.
2. The second option is to make a special tool from wire. Take a piece of thick wire that will hold its shape well. Its length should be equal to the height of the door. You can take it a little longer, about 3-4 centimeters, to make a hook bent at 45 degrees. Carefully inspect the door; you need to find the place where the edge of the rubber seal is located (between the window and the door body). Bend the seal to get inside the door. A couple of centimeters of free space is enough to lower the wire. It should collide with the locking mechanism, which you need to go around and plunge the rod below. After this, move the wire to the center and feel the lock lever with the hook, pull it up.

What do you need for work?

A similar connection diagram for the trunk button attracts many.

To realize your idea, you need to prepare materials and tools.

The set consists of:

• electric drive (activator) of the luggage compartment lock;
• universal 4-pin relay;
• fuse blocks;
• fuse;
• wires;
• female type terminals;
• trunk opening buttons;
• heat shrink tube;
• electrical tape;
• plastic clamps.

The block is placed for safety reasons. Mounted on the positive wire. The fuse can be taken as standard, 10 Ampere. Do not need anymore.

Determine the length of the wiring individually. But practice shows that 5-6 meters is enough with a margin.

At any car market it will not be difficult to buy the entire set. It will cost 600-800 rubles. Maximum 1000 rubles.

Connecting an electric lock to an alarm system

It is recommended to install an electric locking device on the car yourself according to the following scheme:

1. Carefully read the installation diagram in the attached documentation. Perform marking work on the trunk lid. Prepare mounting holes.
2. Install and secure the electric lock drive to the trunk lid of the car. Fit and adjust the electric lock drive rods to the locking device. Connect the rod to the closing mechanism and secure it.
3. Disconnect the battery terminals. Lay out the electrical wiring according to the connection diagram and connect. Use a multimeter to check the correctness and reliability of the electrical connections. Connect the corresponding connectors of the car alarm control unit and the electric lock.
4. Replace the car battery terminals and secure them. Check the operation of the trunk lock, installed by yourself, for correct operation. If necessary, make adjustments and repeat the installation.

Reliable operation of the electric lock is ensured by duplicating the activation of the opening and closing functions. To duplicate the functioning of the trunk lock, experts recommend installing buttons in the cabin that are responsible for the operation of the locking device. The button is located in the cabin in a place convenient for the driver, in which it does not have much significance. The main thing is the correct connection, which is monitored with a multimeter.

Equipping a domestic car with an electric trunk drive

If you install an electric drive for opening and closing the trunk on a domestic car (for example, a VAZ), the basic elements of the mechanism alone, which are already far from cheap, will not be enough. You will also need to install a trunk closer. Therefore, this method of improvement is irrational.

To bring this idea to life, you need to buy two ESP mechanisms (for example, consider products costing about three thousand rubles), a trunk lid control button (type 21100-3710620, cost 50 rubles) and a car window closing module (brand DenUp-RWC702m, price – 500 rubles).

In our example, power windows are installed in the luggage compartment of the Lada Priora using a simple connection. The rear edge of the ESP rail is connected by a threaded connection to the crossbar at the back of the seat, on which the shelf rests. The front end of the window regulator bracket with a welded nut is screwed to the rear window mounting beam. To do this, a groove is cut in the beam into which an M6 nut would fit.

As a result, the assembled structure works without problems when you press a button specially located in the interior or on the remote control.

The mechanism of two ESPs is free of these troubles. In some cases, the lock position will need to be adjusted.

The main reasons why the trunk of a car does not open

Used vehicles mean not only freedom of movement, but also constant unpleasant surprises presented by the car to its owner at the most inopportune times. One of these troubles is the failure of the luggage compartment lock, when the locked lid cannot be opened. The main thing in such a situation is to be concentrated and not to use everything that comes to hand to open the trunk. It’s better to gather your thoughts and try to remember if you’ve encountered a similar situation with your neighbors in the garage or if someone you know told you what to do if the tailgate doesn’t open.

The main reason that the trunk does not open is that the locking mechanism is clogged with dirt flying out from under the wheels of the vehicle while it is moving. In the rear part of the body, this creates a certain turbulence that picks up water, snow and dust from the road. And even despite the fact that the lock is protected by a special screen, miniature particles penetrate inside, rendering it unusable.

Some cars are equipped with a central locking system, which is responsible for simultaneously closing all doors. Often the reason for the inability to open the luggage compartment lid is a breakdown of the electric drive responsible for activating the latch of the locking mechanism. In such a situation, the problem can be solved with a simple key, which is inserted into the keyhole and turned clockwise while pressing the button. But if the key cannot be inserted all the way due to the accumulation of a large amount of dirt in the locking mechanism, you will have to get to the luggage compartment through the passenger compartment.

In addition, it will not be possible to open the trunk of a car if the lock itself simply fails. In such a situation, all attempts to open the lid from the outside of the machine will fail. For this purpose, you need to learn how to unlock the luggage compartment from inside the vehicle.

All about the roof rack VAZ 2107

Cars of the VAZ “classic” family enjoy well-deserved love, including as economic “horses”. These cars carry trailers, building materials stick out of the windows, and, of course, every self-respecting summer resident has a special roof rack for transporting oversized and long cargo.

First of all, you need to decide on the dimensions of the VAZ 2107 trunk in order to know what maximum dimensions of cargo can be placed in the trunk with the lid closed. Here they are:

Everything that extends beyond these dimensions must be placed on the roof of the VAZ 2107 and transported on the top, removable trunk. This is especially true for long items. Materials such as boards, sticks, floor slats, if they do not exceed 4.5 meters in length, may not be marked with red marker flags. In the event that they protrude beyond the front and rear bumpers, they must bear the oversized load mark. This is especially true at the rear end.

There is an explanation for this: the front end is clearly visible to the driver, and he himself makes sure not to drive too close at the traffic lights.

The roof rack of the car is designed for a weight of no more than 50 kilograms. If the driver is sure that the road will be perfect, without the slightest holes, bumps and vertical vibrations, then you can put 75 and even in extreme cases 80-90 kg, but no more. Carrying heavier loads will cause deformation of the body structure, and this leads to disruption of the opening and closing of doors.

The photo shows an old trunk that was produced in the USSR. Its weak point is its “bowl-shaped” shape with raised edges. On such a trunk it is difficult to transport barrels placed on the roof, sheets of cellular polycarbonate rolled into cylinders due to the small number of points of contact.

Currently, all “classics” have high-strength and lightweight roof racks that fit all car models, from VAZ 2101 to VAZ 2107. They are made quite durable and lightweight, and are coated with anti-corrosion powder paints.

The supporting system itself, as a rule, is hollow box-shaped bars made of strong sheet metal, square in cross-section, which are located in a single row, in the amount of 6 - 8, connected at the ends by supports that give rigidity to the structure. Four support mechanisms, which have different designs, are attached to the supports. Most often they are made using eccentric - tightening screws.

In order not to scratch the profile of the VAZ 2107 drain, to which the trunk is attached, the contacting parts are equipped with inserts - polyethylene liners.

When installing a trunk on a VAZ 2107, you must follow two rules:

• The edges of the trunk should be at an equal distance from the windshield and rear window - this ensures correct alignment and distribution of the load on the roof;
• When tightening, you must maintain uniformity. There should be no unevenly tightened eccentrics;

It is even more important to follow the rules for securing cargo on the trunk.

The most important thing is that the loads are securely fastened in the anteroposterior direction

When the vehicle brakes in an emergency, heavy loads occur and cargo can be torn off the trunk. When driving with a loaded rack on roundabouts and long turns, you need to drive slower than usual and evenly, otherwise the angular acceleration may be too strong and the load will be torn to one side. When transporting long boards and whips, you must be very careful when starting, accelerating and braking, as the ends of the whips “play” and rock the car, causing vibration. Particular attention should be paid to transporting bulk cargo in strong winds - if possible, you should avoid this and wait for calm weather; Loads with a large area and resistance (rolled covering material, empty barrels) must be secured especially carefully; While driving, listen carefully to the sounds on the roof. Take the time to go out several times and check the reliability of the fastening of the cargo and the trunk itself.

By applying these simple rules, you can avoid troubles associated with a sudden drop and damage to the load, or - even worse - creating an emergency situation on the road.

System TIDA-01424

The block diagram of the TIDA-01424 reference project is shown in Figure 3. The main elements of the board are two PGA460-Q1 ultrasonic rangefinder microcircuits, which perform all the main work associated with analog signals.

Rice. 3. Block diagram of TIDA-01424

The measurement results, which are essentially the distance to each object detected by the sensor, are compared to user-defined optimized threshold levels and used to make subsequent decisions. The flexibility of the system is due to the ability to receive digital data directly from the PGA460-Q1 rangefinders via the USART serial interface and use them as input data for the gesture recognition algorithm.

The main components of the analog part of the system, including two rangefinder chips PGA460-Q1 with matching ultrasonic transformers and other necessary wiring, a 3.3-volt LDO stabilizer TPS7B6933-Q1 and a TPS3700-Q1 monitor with a power intelligent power switch TPS1HA100-Q1 are mounted on a compact double-sided BoosterPack format board. A special feature of this form factor is the presence of a 20-pin connector, which carries USART signals and several standard input/output ports (GPIO). This connector is fully compatible with LaunchPad microcontroller boards manufactured by Texas Instruments. It is on such a board, running the MSP430F5529 microcontroller, that the rangefinder signal processing algorithms are implemented, the source code of which is available for free download on the Texas Instruments website.

The system is powered by a standard 12-volt battery. At the same time, the system has protection against polarity reversal, undervoltage and overvoltage, and can easily withstand overvoltages of up to 40 V, which arise, for example, during problems in the vehicle’s on-board network.

In passive mode, with the ultrasonic emitters turned off, the current consumption of the system is less than 100 μA, which allows it to be connected directly to the battery without the risk of significant discharge of the latter.

All system components are designed for use in automotive applications and have a corresponding temperature range of -40...105°C.

The overall system consists of two boards (analog signals and a microcontroller), indicated in blue in Figure 3, and requires the connection of only three external components: two ultrasonic sensors and a power supply. The main technical characteristics of the system are given in Table 1.

Table 1. Main technical characteristics of TIDA-01424

Luxury or necessity

The automatic trunk opening feature is found in many new cars. Drivers like this feature, because you quickly get used to good things. To open the luggage compartment in a car, just press a button in the cabin. The lock comes into operation as a result of the operation of the electric drive.

This feature may seem like a small thing and an insignificant addition until the cold weather arrives. In cold weather, the lock on the trunk often freezes, making opening the compartment a difficult task. You have to spend time defrosting the mechanism. In the case of an electric drive, such problems will not arise. Also, such a mechanism makes car hacking more difficult, which is also an important advantage.

Mostly imported cars are equipped with this function, and not all of them. Domestic manufacturers have only recently begun to equip their models with such functionality. Every car owner can equip his car with an electric drive for the trunk. This will not be difficult to do, but you will still have to tinker.

Installation of a standard electric drive on a Lada

Frets of the “tenth” family of recent years of production are equipped with an electric drive for opening/closing the trunk directly at the factory. Earlier series of cars do not have such equipment, so owners will have to install the electric trunk drive themselves.

Our example involves the operation of the electric trunk drive through a separate button in the cabin. Some alarm systems have an additional ability - to open the luggage compartment, so it is to this system that we will connect the electric drive. For installation you will need the mechanism itself and a mounting plate.

In addition, you will need four meters of electrical wire and a switch button.

Before installing the electric drive, be sure to disconnect the negative terminal of the battery. Then we attach the lock drive and remove the protective casing, first removing the fastening clips. Using pliers, we straighten the rear end of the electric drive, unscrew the screw securing the rod, but not completely. The lock drive rod has been disassembled. Now the compartment cannot be opened from the outside, since the lock unlocking mechanism is disconnected from the lock cylinder.

Next, on the trunk lid amplifier, you should mark the locations for drilling the mounting holes for the electric drive attached to the lock. Using an electric drill, we drill holes with a diameter of 3 mm according to the marks. Then it is necessary to bend the rod and make a U-shaped bracket from 4 mm steel wire of such a width that its edges fit effortlessly into the exit points of the drive shell bosses.

We recommend: How to remove the instrument panel on a VAZ-2114 in 12 steps? Features and detailed instructions

An M4 thread should be pre-cut at each end of the bracket. Finally, we fix the electric drive using the prepared bracket and connect the traction lock to it.

Through the green wire on the electric drive, current flows to the button due to the retraction of the rod. This wire is laid next to the original cable harness. We connect ground to the blue wire, which is negative. You can get power from any exposed area of ​​the car body. The interior button is installed on the dashboard in the left corner of the mounting block.

The operating voltage will be connected to it from block Ш1 (pin 2). After assembly, you can check the functionality of the system by pressing the interior button. Everything should work smoothly.

Alternative trunk opening for VAZ 2107

Many owners of domestic cars, due to the lack of opportunity to purchase a more expensive vehicle, are trying to make their cars more comfortable. One of the options for improving the functionality of the VAZ 2107 is to control the trunk lock from the passenger compartment. This can be done either using a button or using a cable, which eliminates the need to open the mechanism with a key.

Opening with a button

As the owner of the “Seven”, equipping the car with a device for opening the trunk with a button will not be difficult. The positive aspects of the electric drive include the following:

• convenience;
• practicality;
• following fashion.

Installing a trunk lock control button allows you to control the mechanism from inside the car.
Some motorists believe that such an option on the VAZ 2107 is useless, but it’s still worth trying and seeing the usefulness of such a device. If you have decided to install an electric trunk drive, then first you will need to prepare the necessary parts:

• four-pin relay and a special terminal for it;
• activator;
• wires;
• button;
• female and male connectors, as well as electrical tape and heat shrink.

To install an electric lock on the trunk lid you will need an electric drive, wires, connectors, terminals and a button.

The activator is an electric drive, the operation of which is based on retraction or repulsion, depending on the installation diagram. First you need to remove the lock and install the drive rod. In order to be able to influence the lock tongue, you need to drill a hole in the side of the mechanism and bend the rod itself slightly. Once the rod is secured, the lock can be put in place.

The trunk lock on the “seven” can be opened using a cable pulled into the car’s interior. To implement this idea you will need:

• cable 4 m long and 1.2 mm in diameter;
• braid 4 m long from bicycle cables;
• braid ends and cable clamps.
