How to connect fog lights to a VAZ 2109

Good headlights are one of the most important options in a car, responsible for the safety of all road users. To improve the light on the VAZ-2109, you can install additional fog lights. Fog lights play a big role in lighting in adverse weather conditions - be it snowfall, fog, rain, etc. They are great for lighting in the evening, and during the day they can duplicate the functions of low beam headlights.

They also increase the viewing angle of the fog lights at night, additionally illuminating the side of the road so that the driver can notice an obstacle in time. The installation instructions, which we will describe below, will also be useful to owners of other domestic cars: VAZ-2108 and VAZ-21099 with a “high” panel.

Fog lights on the VAZ-2109: installation and connection method

Good headlights are one of the most important options in a car, responsible for the safety of all road users. To improve the light on the VAZ-2109, you can install additional fog lights. Fog lamps play a big role in lighting in adverse weather conditions - be it snowfall, fog, rain, etc. They are great for lighting in the evening, and during the day they can duplicate the functions of low beam headlights.

Headlight adjustment

Adjusting foglights is a responsible matter. If the headlights are not adjusted correctly, there is a risk of causing inconvenience to other road users and creating a safety hazard. Rough adjustment of the PTF can be done independently. To do this, select a horizontal area near a white vertical wall. The verticality of the wall can be checked by eye, but it is better to verify the horizontality of the site using tools. A two-meter building or water level is suitable for this. Having found a suitable place, place the front of the car against a white wall at a distance of 4-5 meters from it. It will be good if direct rays of bright sunlight do not fall on this wall. Measure the distance from the center of the headlight to the ground. Turn on the fog lights. Measure the distance from the center of the light spot to the ground. The center of the spot should be located 2-3 centimeters below the center of the headlight.

This adjustment is quite rough. For more accurate results, you need a specialized stand at a service station. If you order the installation of a PTF at a service station, the adjustment will be included in the price automatically and will be carried out without fail.

General information about installing PTF on a VAZ-2109

To install fog lights on a VAZ-2109, you will need the following parts:

wire with a cross section of 1.2 mm. sq. The wire must be long enough to extend from the fuse box to each headlight being installed;
female terminal (wide) – 4 pcs;
female terminal (narrow) – 1 piece;
terminal with a hole in the middle – 3 pcs;
relay, block, wires;
headlight activation button;
two fog lights.

Automotive stores sell special kits for installing PTFs. The kits contain everything you need for successful installation and connection of headlights on a VAZ-2109.

If you couldn’t find a ready-made kit or like to do everything yourself, then you need to assemble the relay with a block and wires. There are four wires coming from the relay. Two power wires are crimped with wide female terminals. The remaining two are control contacts.

One of them is crimped with a narrow female terminal, the second with a hole - it makes a connection to ground.

The power group wires from the block to the headlight are crimped in this order: on one side there is a wide terminal, on the other there is a block for connecting to the PTF. The second wire in the block is the ground wire.

Installation kit

To implement the project you will need:

two fog lights with mounting brackets;
normally open relay for connecting lighting devices;
button for turning on fog lights;
single-core wire with a cross-section of 1 sq. mm, approximately 4 meters long;
fuse 16A;
connection diagram;
contact blocks - if they are not included in the kit with headlights and relays.

If you already have something from this set, purchase the rest. And if you have to buy everything, then consider purchasing the entire boxed set. It includes everything you need, and there are also detailed installation instructions.

Connecting fog lights on a VAZ 2109 will require certain tools. You will need a 10 mm wrench, a screwdriver, side cutters, a shoemaker's knife for stripping wires and electrical tape. This is the minimum set. It is sufficient if twisting technology is used to connect wires.

Another option for connecting PTF, which most experts recommend, is soldering all connections and using heat-shrinkable materials for insulation.

Installation of fog lights on a VAZ-2109

First of all, we install the PTF activator button. Car models that have a “high” dashboard have a standard place for this.
Remove the speaker masking grille and unscrew the speaker itself. Behind it are wires with chips for connecting the power button and an indicator of their operation.
We make room for the power button, connect all the chips and install back the speaker and masking grille.
Then we connect the mounting block. It is located under the hood and looks like a black box. We unscrew the fasteners and slightly lift it to provide access to the contacts.
Then we stretch the wiring from the PTF and from the relay (with the exception of the ground wire) to the mounting block.
We disconnect contacts Ш8 and Ш7 from the “black box” and connect the terminals as shown in the diagram:
We install the connected connectors back into the mounting block.
After this, we place the fuse box in its place. We fix the relay on the body, and install “ground” under the bolt with which we clamp the mount. Be sure to clean the paint from the contacts.
Next, we attach the power wires to the contacts of the fog lights. We immediately provide the presence of “ground” by connecting to the metal parts of the car.

The last stage of installation will be reliable fixation of the PTF. To fix the headlights well, we cut holes in the steel insert near the bumper mount. The good news is that some types of bumpers have the necessary holes and the headlights can be mounted on special brackets. Be sure to securely fix the new headlights so that they do not shake when driving over uneven surfaces.

An important part of installing new car lighting is adjustment. After installing and connecting the equipment, all that remains is to set the correct lighting angle and enjoy your trips.

PTF power button

The choice of installation location for the fog lamp switch depends on whether your car has a high or low dashboard. If it’s high, you’re lucky, your option has a standard place for the PTF switch on the VAZ 2109. It is located to the left of the steering column between the rear fog lamp switch button and the rear window heating switch button. This place is closed with a plug. To install the button, remove the decorative panel covering the left speaker of the audio system and remove the speaker itself. This will give you access behind the dashboard necessary to install the button. Connect the PTF activation block and the indicator block for this activation, and then install the button in place.

If you have a low panel, it will be more difficult to install the button. There are two options. The first is that you can parallel the activation of the PTF with the activation of some other system, for example, rear fog lights. The second is to organize a special place for this button. Such a place could be a muffled socket under the central air duct of the ventilation system, next to the heated glass switch of the fifth door.

To install the button in the low tidy, you will have to dismantle the panel located between the central nozzle of the ventilation/heating system and the heater controls.

How to install fog lights on a VAZ 2109

Appearance of fog lights on a VAZ 2109:

Installing fog lights on a VAZ 2109 is not difficult if you know how to read simple diagrams and have basic installation skills. The connection diagram is standard, and if you look closely, you will even see the wiring that lies in the engine compartment, goes to the button in the cabin and to the fuse box.

Need for installation

It’s good when on the latest model cars everything is initially provided for these lighting devices. All that remains is to buy equipment that corresponds to the technological description, and without further ado, insert it into standard niches, connecting the wires provided by the manufacturer.

What if there is none of this? You can go to the nearest car service center and pay the technician to wait for the results of the work. Well, after reading this article, you can do it yourself. The main thing is to have at least some skills in working with the tool.

Installation materials and requirements

So, first you need to stock up on the following tools and materials:

Directly fog lights.
About three meters of single-core wire (red) with a cross-section of 0.75 squares.
Relay with normally open contacts, a metal plate for fastening and a block with wires.
Button (most likely, it is already installed next to the heated rear window switch).
At least five screws.
Screwdriver, 10mm wrench, utility knife and pliers.
Heat shrink insulation and electrical tape.
16 Amp fuse and socket for it.

Before you begin, you should decide on the mounting location for the VAZ 2109 fog lights themselves; pay attention to the lower part of the bumper. If you look closely, you will find places for fastening there.

There is just one drawback - on older cars it is sometimes difficult to install them in these places; you have to contrive and screw them directly to the bumper. You just need to take into account some of the requirements of GOST, which has been in force since 1975 to this day:

The distance from the side surfaces of the car body to the nearest edge of the fog lamp should be a maximum of 40 cm.
The height of the fog lights (from the ground surface to the bottom edge) is from 25 cm.

To avoid problems with law enforcement agencies (read traffic police inspectors), you need to adhere to these requirements. But the “attention” of inspectors is not so dangerous, much worse is the incorrect dispersion of light as a result of incorrect installation. Fog lights will either blind oncoming drivers or be ineffective in poor visibility conditions.

Features and design of PTF

Conventional headlights on the VAZ 21099 in bad weather work in such a way that they reflect light from raindrops or grains of snow, as a result of which the rays fall directly into the driver’s eyes. This, in turn, contributes to the deterioration of the visibility of the road surface. If we talk about PTFs, their design is somewhat different. Fog lights on the VAZ 2109, in accordance with the diagram, should be located close to the road surface, since fog does not fall on the asphalt. As a result, it turns out that the fog lights of the VAZ 2109 shine as if under fog, forming a flat beam of illumination, thus illuminating exactly the required section of the road.

We recommend: Replacing rear shock absorbers of VAZ 2114

Fog lights on the VAZ 2109 with or without xenon are placed in a symmetrical manner, necessarily below the main optics. That is, the headlights on the VAZ 2109 should be higher in any case. The distance of the PTF from the road surface should be 25 cm, and from the dimensions and turns the distance should be at least 40 cm. If you decide to install lensed PTF with or without xenon, these requirements should be taken into account. According to some car enthusiasts, installing xenon in the lenses of daytime running lights will replace fog lights, but this is a wrong opinion.

In order for PTFs with lenses to shine normally, they must be correctly adjusted. Please note that if the angle of the lights is too small, their use will be pointless. Moreover, such an adjustment can cause inconvenience to drivers of oncoming cars. As for lighting, it should be either yellow or white, which is why many car owners install xenon in their lenses. The use of red, green or blue light bulbs in PTF is not allowed, since their efficiency is minimal (the author of the video is the Kakto SO channel).

How to install fog lights on a VAZ 2109?

So, the installation begins. To carry it out, you must first install the headlights in the intended location. After this, take the wire and connect it to the right fog lamp (positive terminal). Lead the wire into the engine compartment and connect it to the harness running under the radiator. Bring this to the left fog lamp of the VAZ 2109, and then make a connection with its lamp. Insulate all bare areas; for this it is best to use heat shrink.

Connection to standard mounting block 2109

Next, the wire must be brought to the installation site of the electromagnetic relay, whose normally open contacts serve to supply voltage to the fog lights of the VAZ 2109. The plus from the battery comes to one terminal through a 16 Ampere fuse, from the second it will be removed and go to the fog lights connected in parallel.

Two wires are connected to the contacts of the relay coil: one immediately to ground, and the second lead to the button in the cabin. Now all that remains is to supply negative power to both fog lights of the VAZ 2109, and apply positive power to the second contact of the button from the ignition switch (to prevent the fog lights from turning on when the ignition is off).

PTF connection - diagram for any car

Now I would also like to make a visual notification about the inclusion of fog lights on the VAZ 2109 on the dashboard. Unfortunately, not all modifications have an indicator lamp built into the panels. But you can cheat - if you have a carburetor, and there is a lamp indicating an engine error, then you can use it (as an option - a seat belt indicator).

This lamp must be connected to the break in the wire going to the ignition switch. You will get a closed circuit, but if the indicator lamp or relay coil fails, the fog lights on the VAZ 2109 will not turn on.

Detailed instructions for installing fog lights

If you decide to install fog lights on a VAZ, then first you should purchase the optics kit itself. As mentioned above, xenon can be installed in VAZ 2109 headlights with lenses; if you want to install it and connect it right away, then buy the appropriate kit. There is a huge variety of lens headlights on the market, so when buying lenses, pay attention to their build quality. They must be as durable and reliable as possible so that their operation does not cause problems later.

Replacement procedure

How to install and connect fog lights on a VAZ 2109?

The procedure is described using the example of a car with a high panel:

First you need to mount and connect the foglight control button. If your “nine” is equipped with a high center console, then it already has space for mounting the corresponding button. If the panel is low, then this is also not a problem - it also has a corresponding place, to the right of the button for turning on the low beam and dimensions. Remove the grille located to the left of the steering wheel, after which you will gain access to the connector for turning on the PTF. The plug from the center console can be removed, and instead you need to install an optics control button that connects to the on-board network. Having done this, put the grille in place.
Now you need to open the engine compartment and unscrew the mounting block. You need to bring the wiring from the PTF to it and connect it to the appropriate connectors. In addition, the wiring must go from the place where the relay will be installed to the block. Please note that the ground wire should not be touched.
It is necessary to disconnect pins Ш7 and Ш8 from the block, which are located in close proximity to each other. It is necessary to install pre-prepared terminals into these connectors, using the diagram below. If you do not have fog lights, then these terminals should be free.
Next, the block is put in place and the relay is installed; it can be installed on the car body. Mass is carried under the bolt. It should also be noted that before installation, the place where the contact will be must be thoroughly cleaned of paintwork, otherwise there will be no “ground”.
After completing these steps, the power wires must be connected to the fog optics. The ground is connected, that is, the wire to the body, and it is desirable that the ground be as close as possible to the PTF, in a convenient and dry place. If the contact of the optics with the vehicle body is unreliable, this may lead to malfunctions of the headlights, and their overall functioning will be unstable.
Now you need to install the fog lights themselves; to do this, you need to make the appropriate holes in the front bumper. It is best to drill near the bumper mounting screws. If there is a place in the bumper specially designated for these purposes, then PTFs are placed there. Ensure the best possible fixation of the optics on the bumper to prevent vibration and shaking. After everything is ready, all you have to do is adjust the light output.

Fog lights for VAZ 2109 connection.

The method of connecting fog lights is very simple and will not take you more than an hour. Typically, most of the time is spent installing them on the car itself.

To connect we need:

The fog lights themselves for the VAZ 2109. (Well, or any others that please your heart)
Power wires with a cross-section of 1 sq. mm and long enough to stretch them from the block to the front bumper, i.e. the fog lamp itself.

3 terminals: narrow and wide (female) and one for ground.
PTF on/off button.
PTF transmission with block and wires.

All this can be bought at any spare parts store, namely a kit for connecting fog lights. The asking price is 1500 rubles.

It looks like this:

Installation of headlights and wiring

The standard bumpers of the VAZ 2109 provide special places for mounting fog lights. If your car still has its original bumpers, it is best to fix the headlights in their original places. If they were changed, consider fixing the fog light brackets not to the bumper, but to the car body. Attaching to a bumper, especially a non-standard one, increases the risk of misalignment. This may result in blinding oncoming drivers and the risk of losing lights. Do not forget about the requirement to place the PTF no lower than 25 cm from the road surface and no further than 40 cm from the vehicle’s overall dimensions.

The process of connecting fog lights on a VAZ 2109.

First, we will need to connect the on and off button for our fog lights. The regular location is shown in the photo below.

When disassembling the grille and dismantling the column, we find the factory terminals for connecting our headlights.

We install our button instead of the plug and connect the connectors. We're done with the button, you can assemble the grille.

Now we open the hood lid and unscrew the mounting block.

Afterwards, we select a place to install the relay and draw wires to the mounting block except ground. We attach the mass under the same bolt securing our relay. Also immediately run the wires from the place where the fog lights are mounted.

Now, using the diagram below, we connect the fog lights and relays to connectors Ш7 and Ш8.

We assemble everything in the reverse order - connect connectors Ш7 and Ш8 and screw the mounting block.

After installing the fog lights, we connect our wires to them and do not forget about the ground.

Fog lights are usually attached to the bumper mounting points. Tighten it harder.

What you need to buy

If you are installing fog lights (VAZ 2114, you can watch the video in the article), then first of all, of course, you will need lighting equipment. You need to select according to the characteristics of the car. For example, in VAZ models such as 2110, 2112, 2114 and 2115, there are plugged technological holes in the bumper, and accordingly it makes sense to purchase lights based on their shape.

Installing fog lights on a VAZ 2109

Fog lights are an element of the road illumination system that will allow you to better navigate the road in difficult weather conditions in your VAZ 2109. Due to their glow, PTFs effectively illuminate the path in fog, snow, and rain. Plus they inform oncoming cars about your approach.

Installing a PTF is important primarily from a safety point of view. Although many people install them to improve the appearance of the car. Combine both functions? Why not.

PTF in all its glory

Carrying out the process

If you have a VAZ 2106, installation of fog lights can be carried out in a short time. First you need to install the lights themselves on the car. Here everything depends on the imagination of the car owner. Some people attach them near the radiator grille, some hang them under the front bumper, and some hang them on the bumper. This is a personal matter.

The main thing is to securely fasten it, this is what installing fog lights (VAZ 2114) with your own hands is all about. Now installation of electrical wiring. You need to secure the relay in the engine compartment to turn it on. And there are no special restrictions here, the main thing is that wires can be connected to it, and away from the exhaust manifold and radiator. That's all the requirements. And now attention is the most important thing! The main trick here is to connect the button and relay correctly.

If you purchase VAZ 2115 fog lights, you can install such equipment yourself. A standard general purpose relay has four legs numbered - 85, 86, 87 and 30. Regarding the relay, any car enthusiast should know that contacts 85 and 86 are an electromagnetic coil.

Current is supplied to it, the core acquires the properties of a magnet and closes contacts 30 and 87. Therefore, you need to fasten it to ground from contact 85 and from 85, run the wire into the interior to the button. Apply “+” to pin 30 with the battery. And already from the 87th contact, bring out two wires, cutting in the fuses. When a VAZ 2110 is available, do-it-yourself installation of fog lights can be done in the shortest possible time.

Connect the button as follows: one contact goes to the relay - pin 86, connect the second to the “+” of the ignition switch, having previously called it with a test lamp. Carefully insulate the joints and you're done. You can use it. Any car enthusiast can easily install fog lights on a VAZ 2109. The main thing is to use the prescribed technology.

Tools and materials

According to the current traffic regulations, fog lights can act as an alternative to low beams when used during the day.

If you install and adjust the PTF correctly, they will be able to additionally illuminate the side of the road. So, if visibility is poor, you will notice pedestrians and animals suddenly jumping out in time.

To carry out the work, you will need a certain set of devices.

Element

Quantity

The length is calculated based on the fact that it is enough to stretch from the fuse block to each PTF. The cross section must be 1.25 sq. mm.
