How to install and connect fog lights on a VAZ 2113, 2114, 2115 using your own hands

Print this article Font size 16

Fog lights or simply PTF are an important element of the lighting system for a car. Alas, not all manufacturers equip their cars with these devices. AvtoVAZ with its model 2114 is no exception. PTFs for the fourteenth are available only for an additional fee and in the most expensive configuration.

Not everyone sees the point in buying the most complete version just to get PTF. An excellent solution is to install foglights yourself.

Beautiful and effective

What are fog lamps for?

The main task of the PTF is to illuminate the space in front of the car. Correctly adjusted “fog lights” can illuminate a section of road 10–15 meters long. This distance is quite enough for safe movement by car in poor visibility conditions. The switching on and off of such lighting devices must be fully controlled by the driver.

Adjustment of fog lights is carried out during their installation. The procedure does not take much time, but requires care and precision. You can install the rear and front PTFs yourself.

Headlight installation

Since the standard bumper does not have seats, they will have to be done independently. For this you may find it useful:

Drill with drill;
Jigsaw;
Ratfil;
Measuring tools (tape measure, ruler, etc.);
Marker;

The installation of fog lights is carried out with the bumper removed. Markings are first made on a bumper that has been cleaned of dirt. The optimal installation location is at the level of the lower air intake, but at a certain distance to the side of it. It is advisable that PTFs be placed strictly under the headlights.

First, we determine the distance at which the fog lights will be removed from the air intake. Then we figure out what size holes need to be cut. Decorative “glasses” will help with this. They consist of two halves - the outer (which is decorative) and the inner (which secures the outer part and the headlights themselves).

The outer half of the glasses has a fitting ridge that should fit into the hole in the bumper. To determine the size of the hole, the dimensions of this mounting protrusion are measured. Then we apply markings with the appropriate dimensions on the bumper.

Having completed the markings, we proceed to cutting out the holes with a jigsaw. After this, it is advisable to correct the edges of the hole with a file.

It is important to ensure that the outer part of the glasses fits tightly into the hole

We fix the fog lights in these holes using bolted connections. All that remains is to attach the “glasses” over the headlights.

After installing the fog lights, we install the bumper on the car. This completes the first stage.

Installation diagram of fog lights

The connection of fog lights is carried out according to certain rules. They, first of all, relate to the placement of PTF on the car. The locations for installing headlights are strictly defined.

Layout of daytime running lights

Manufacturers of modern car models pre-mark the PTF installation locations on the bumpers. As a rule, such lighting elements are most often available in the luxury version of the car. If the headlights themselves are missing, then their installation sites are closed with special plugs.

Distance at which fog lights can be placed

The process of connecting fog lights on a VAZ 2114

When you have prepared everything, you can proceed to the stage of installing and connecting the fog lights. It is best to perform installation according to the instructions presented below, following the sequence of actions:

Connecting fog lights on a VAZ 2114 begins with determining the location of the button on the dashboard. You can choose any one, but it is best to install it in the standard version by removing the plug.
Remove the grille from the front panel. Behind it there will be two blocks used to turn on the headlights, indicate the operation of the fog lights and illuminate the button. The PTF connector is installed from the factory, regardless of the vehicle configuration.
Having placed the button in the chosen location, we connect it, and then put the panel back together.
We need to unscrew the fuse block, lift it and find two blocks numbered 7 and 8.
We lay a harness of 4 wires with contacts that should be included in the kit to the block from the relay installation location.
Afterwards we connect the relay. We will need a diagram for connecting fog lights on a VAZ 2114. We connect the wire from the 30th contact of the relay to block No. 8 of the mounting block to terminal 8. Contact 87 goes to terminal 1 of the same block. 85 is connected to block No. 7 at terminal 17, and 86 is supplied to ground.
Voltage to the fog lights is supplied from the 2nd and 3rd contacts of the block at No. 8, and the ground is mainly secured to the nut of the headlights.
From the 1st block from the 6th contact there is a wire to the 1st contact of the external lighting switch, and from the 4th block of the mounting block from the 4th contact to the 2nd contact.
Then you need to connect the control button. Pins 5 and 19 of pin 4 of the block are involved here (you can see more details in the diagram described above).
Remember that the connection must be made through a button and a relay!
Next, you should install the fog lights in the right place. If you already have a standard bumper that has holes for fog lights, then just install them in the stock place.
If not, prepare the holes. To do this, it is better to use GOST, which states that PTFs must be installed at a height of at least 250 mm above the ground, and no more than 400 mm from the overall width.
Before cutting, it is better to find the owner of a VAZ 2114 with PTF already installed, measure the bumper and prepare a stencil for the holes.
Afterwards we transfer all the dimensions to our bumper. We trace along the stencil and start cutting. Once the hole is cut, it is worth finishing it with a file to even out the edge.
If everything is done correctly, you can install “glasses” in the bumper, and if everything fits, it will not differ from stock.

Auto-assistance

When driving a VAZ-2115 passenger car, regardless of the time of day, the side lights, as well as the headlights, must be turned on. This is a requirement of the Russian Traffic Rules that every driver must comply with. Therefore, the electrical circuits of side lights and brake lights operate through the K4 lamp control relay, the task of which is to warn the driver with a light and sound signal that at least one of the lamps of the above listed electrical circuits is not turned on. This will force the driver to get out of the car and determine which side light lamp is not on and begin to search for the problem.

On a VAZ-2115 car, the side light lamps in the rear lights often stop working. This is due to the occurrence of leaks in the lamps, as a result of which moisture gets inside, which leads to oxidation of the plug of the block or the track on the flexible circuit board, through which voltage is supplied to the lamp contacts.

There are cases when, after moving the exterior lighting switch to the first position, not a single side light lamp lights up. The search for such a malfunction will have to begin by checking the presence of voltage at terminal 1 of this switch. It should be +12 volts, even with the ignition off.

If this terminal is de-energized, then you will need to sequentially check the voltage at terminal 6 of connector X8, and then at terminal 6 of connector X1 of the mounting block. If there is voltage at these terminals, the culprit for the lack of power at terminal 1 of the outdoor lighting switch will be the pink wire connecting it to terminal 6 of connector X1 of the mounting block.

Well, if there is voltage at terminal 1 of the external lighting switch, the culprit for the side lamps not turning on may be the switch itself or the K4 lamp control relay. To make sure that the switch is out of order, you need to move it to the first on position and check for voltage at its terminal 2. If there is no voltage at this terminal, then the outdoor lighting switch will have to be replaced.

If fuse F10 (7.5 A) blows, the front and rear side lamps on the left side of the VAZ-2115 car will not light up, and if fuse F11 (7.5 A) fails, both side light bulbs on the right side of this vehicle will not light up. car. The blown fuse F10 can be determined instantly, without even looking into the mounting block, since the backlight lamps for switches, heater control levers, cigarette lighter, and ashtray immediately turn off, because it also protects these electrical circuits.

Checking the functionality of the PTF

After the work has been carried out to connect the fog lights on the VAZ 2114, it is worth checking their functionality. If everything is done correctly, then when you turn on the side lights and press the button, voltage will begin to flow to the relay, after which the lamps should light up. If you turn off the headlights, the fog lights should also go off, regardless of the position of the button. If everything is done correctly, then the next step is to adjust the light beam so as not to blind oncoming drivers. Having done this by eye, the light from the fog lights should be 10-15 meters ahead of the car, but no more. It is best to contact a service station with special equipment to adjust the headlights, or read the instructions in more detail on how to do it yourself. Useful: How to adjust the headlights and PTF on a VAZ 2114? Correct adjustment is the key to safety on the road, not only for you, but also for other road users. By installing fog lights, car enthusiasts want to get not only direct functionality, but also improve the appearance of the car. Since public roads require driving with the optics always on, fog lights can take over this function. Thus, you can install high-quality lamps in them and spend less on constantly replacing burnt-out light elements in the headlights. As described earlier, at the most unexpected moment, PTF can help you out when visibility deteriorates when driving along the highway during fog.

How to choose PTF

When choosing fog lights, you should pay attention to two parameters:

Color. PTF glasses should be either yellow or milky. Rays of this spectrum are most effective in foggy environments. Moreover, the traffic rules allow the installation of PTFs only in these colors, therefore, by installing blue or other “fog lights”, you can receive an administrative fine for violating the rules.

Advice: with PTF with yellow glasses, it is optimal to use white incandescent lamps. And, accordingly, yellow incandescent lamps are suitable for “foglights” with milky glass.

Marking. The presence of the letter “E” on the headlight (possibly with numbers) indicates that the headlights are certified in the EU. This should be followed by a Latin letter indicating the name and type of the lighting device. For PTF it should be the letter “B”. What is included in the PTF kit

The standard kit for installing fog lights includes:

headlights with bulbs;
set of wires;
electromagnetic relay;
PTF power button;

Installation of PTF on VAZ 2114

There are three ways to install PTF on a car:

Buy a new bumper with installed fog lights. This is the simplest, but most expensive solution. Such a bumper can be purchased at a tuning studio, where they will install it and connect the VAZ 2114 PTF.
Buy a VAZ 2115 bumper, suitable fog lights and install and connect the parts yourself.
Buy suitable PTFs with cladding, embed them into a standard bumper yourself and connect them to the on-board network.

To replace or modify a standard VAZ 2114 bumper, it must be removed from the car. The holes in the bumper should be marked using a stencil and then cut with a jigsaw or drilled. It is necessary to insert and secure the headlight trim (glasses) into the finished holes. The fastening must be done as reliably as possible, since poorly secured fog lights will vibrate when moving, which will shorten their service life. When the headlights are fixed in the bumper, and the bumper itself is installed in its original place, all that remains is to connect the VAZ 2114 PTF.
