How to connect an emergency button

The turn signal breaker circuit for the VAZ 2101 and their modifications is as follows:

As a connection diagram, we use a diagram from a VAZ 2106 with a six-pin button for turning on the alarm. We'll change this diagram a bit, the overall look will remain the same, but we'll use different anchor points. (This is done to simplify installation and does not affect performance in any way) This diagram looks like this:

Work order:

You can also use an old relay by connecting it as in diagram 2106, but the original relay 2101 uses outdated technology and is very sensitive to load changes, so the process of replacing the relay is described below. We remove the old turn signal relay by unscrewing the nut securing it to the front panel and disconnecting the three wires from it. (the colors of the wires must correspond to the colors in diagram 2101) In order not to lose the nut, immediately put a new relay in this place and lightly screw the nut on. (don’t delay) I hope that you have already decided on where you will install the hazard warning button... If not, then decide quickly, because we are starting to lay wires and pull them to where the hazard warning button will be. My button is located in the console for the VAZ 2107 receiver in place of the potentiometer, but as an option, I was thinking of installing the button in the radio plug in the dashboard. (to the right of the steering wheel)

Relay: Relay contact 2 is connected to the wire removed from contact “L” of the old relay and to contact 7 of the hazard warning button. Relay contact 1 is connected to contact 4 of the hazard warning button. Relay contact 3 is connected to the wire removed from contact “P” of the old relay. We attach the wire from contact 4 to ground (vehicle body). The optimal place is under the relay mounting nut. By the way, after all of the above has already been done, you can tighten the relay mounting nut. (don’t overdo it, the mount is plastic, it can break)

Button: Button pin 4 should already be connected to relay pin 1. Contact button 2 is connected to the wire removed from the “+” contact of the old relay. Button contact 7 should already be connected to relay contact 2. We connect button contacts 1 and 3 to the steering column turn signal switch; the connection order is not important. The locations in the block look like this (there are 8 contacts in the block we need):

Contact button 8 is connected to the positive, which does not depend on the position of the key in the ignition switch. You can use the plus from the cigarette lighter. If the plus is taken from the battery or from the generator, then it is advisable to protect this circuit with an 8A fuse.

That's the whole installation. After this, we tighten the resulting braid of wires with clamps and secure the wires so that they do not dangle or fray. You can attach new conductors with electrical tape to existing braids. We reinstall the instrument panel, restore the connections of the heater switches, dimensions and lighting of the instrument cluster. Now you have an alarm, use it and enjoy it... Thanks for the article, RavenDark. vaz2101.spb.ru

Addition In general, here is the most normal emergency scheme for a penny

note: it is better to use relay 05, not 06 as in the diagram. With 05 relays, the lamp on the dash blinks in time with the turn signals and you can control how many times the “thank you” blinks in traffic. and 06 flashes along with the hazard warning button.

Lada 2101 Cat Basilio › Logbook › Installing an alarm system

I decided to put the emergency lights on my baby because I feel bad that they are missing out on food or giving in to food, and I can’t even thank you!

Installation of alarm systems on VAZ 2101 and their modifications.

I think that many people have had the desire to equip their car with an alarm system. After all, if anyone doesn’t know, the emergency warning system began to be installed on cars of the VAZ family starting with model 2103. But you must admit that sometimes you want to flash the emergency lights to the person who let you pass in a traffic jam, wink at a pretty girl, or simply, almost legally, stop at public transport stop in front of the trolleybus and run to the stall almost without violating traffic rules...

So, for those who are interested in all of the above...

First, I’ll tell you what materials and tools we will need to do this work.

1. Key 10. 2. Phillips screwdriver. 3. Wire cutters. 4. Pliers. 5. Flat screwdrivers. 6. Knife. 7. A lot of patience, because you will remember more than once a certain MOTHER and VAZ designers...

1. Electrical tape or heat shrink tubing. 2. Installation wire (about 5 meters). Preferably pieces of different colors. 3. Turn signal and hazard warning relay from VAZ 2106. (four contacts) 4. Hazard warning button. (six contacts) 5. Relay connector. 6. Connector for connecting a button.

Operating time: 2-3 hours at best

Work order:

We remove the old turn signal relay by unscrewing the nut securing it to the front panel and disconnecting the three wires from it. (the colors of the wires must correspond to the colors in diagram 2101) In order not to lose the nut, immediately put a new relay in this place and lightly screw the nut on. (don't delay)

I hope that you have already decided where you will install the hazard warning button... If not, then decide quickly, because we are starting to lay the wires and pull them to where the hazard warning button will be. My button is located in the console for the VAZ 2107 receiver in place of the potentiometer, but as an option, I was thinking of installing the button in the radio plug in the dashboard. (to the right of the steering wheel)

Relay contact 2 is connected to the wire removed from contact “L” of the old relay and to contact 7 of the hazard warning button. Relay contact 1 is connected to contact 4 of the hazard warning button. Relay contact 3 is connected to the wire removed from contact “P” of the old relay. We attach the wire from contact 4 to ground (vehicle body). The optimal place is under the relay mounting nut.

By the way, after all of the above has already been done, you can tighten the relay mounting nut. (don’t overdo it, the mount is plastic, it can break)

Button contact 4 should already be connected to relay contact 1. Contact button 2 is connected to the wire removed from the “+” contact of the old relay. Button contact 7 should already be connected to relay contact 2. We connect button contacts 1 and 3 to the steering column turn signal switch; the connection order is not important.

After this, we tighten the resulting braid of wires with clamps and secure the wires so that they do not dangle or fray. You can attach new conductors with electrical tape to existing braids.

We reinstall the instrument panel, restore the connections of the heater switches, dimensions and lighting of the instrument cluster.

Now you have an alarm system, use it and enjoy...

Lada Granta: wiring diagram for rear wiring harness devices

The rear part of the car wiring is responsible for the equipment of the stern and sides of the car. all additional equipment is connected exclusively through this part of the highways:

1/2 – contact group for the dashboard;
3/4 – direction indicators;
5 – handbrake indicator;
6 – rear window heating contact;
7 – interior lamp;
8 – indicator of the driver’s seat belt position;
9 – cargo compartment illumination lamp;
10 – fuel pump drive;
11/15 – aft dimensions for the left and right sides;
12 – trunk lid lock drive;
13 – button for turning on the interior lamp;
14 – additional stop chain;
16-19 – door terminal blocks for the rear left, rear right, front left and front right doors;
20 – airbag control drive;
21 – contact group of license plate lights;
22 – on the dashboard;
23/24 – rear speed indicator sensors;
25/26 – seat belt pretensioners;
27 – group of dashboard contacts.

Installing the ignition switch

A new lock on Granta can be purchased at a price of 1,800 rubles. This is the cost of the kit with all the door cylinders and trunk lid. Installation is carried out in reverse order. We first install it on the shaft and try on the casing so that the lock sits exactly in the hole. After which you can finally tighten the fastening bolts.

It is necessary to tighten until the head of the bolt comes off when a certain torque is reached.

After which you can install the casing in place, having previously connected all the power wires.

Preventive measures

In order for the factory wiring of the Lada Grant to serve for a long time and not break, experienced experts strongly recommend following a number of simple rules.

Periodically check all contact connectors and terminals for oxidation and rust. Such damage to the connections can cause a short circuit and a critical decrease in the conductivity of the line, which is perceived by the on-board computer as an error or breakdown.
Use only original consumables and electronic components. The use of counterfeit products does not guarantee the functionality of the circuit. At the same time, some elements, when damaged, cause a voltage drop in the network, which becomes a direct cause of failure of other equipment or a fire.
Use special oil to treat contact groups. The fluid is sold in auto shops or electronics stores. After treatment, the contacts are covered with a moisture-impermeable layer, which increases their service life by 2-3 times.
Carefully monitor the charge level and condition of the battery. The wiring of the Lada Granta critically perceives a significant voltage drop in the on-board circuits. As a result, this may cause damage to the firmware of electronic control units.
