Here are the wiring diagrams for GAZ 3110 1996-2004 onwards External distinguishing features were new fenders, roof shape, hood, aprons, radiator grille. Only the doors remained the same. At first, GAZ 3110 cars were equipped with narrow black bumpers, and since 2000 they have been replaced by new modern bumpers, which began to be painted in body color. They gave the car a more impressive look due to the additional volume. A distinctive feature was the trunk lid, which opened from the bumper itself in order to facilitate the loading of things into the luggage compartment. In 2001, cars began to be painted and primed according to a new system, which made it possible to increase the life of the body. There was also a special version of the GAZ 3110 for taxi services, which had a special coloring, preparation for a taximeter and interior trim made of easy-to-wash materials.

The difference between the ZMZ-402 engine and the ZMZ-4062 engine is the ignition system
The performance of the automotive ignition system (SZ) directly affects the functionality and condition of the vehicle engine. Accordingly, the failure of one of the elements of the system can lead to minor or even serious malfunctions in the operation of the power unit. What is the principle of operation and the procedure for SZ, how to replace the Gazelle ignition switch - read more about this below.

The principle of operation of the Gazelle ignition system
To begin with, consider the principle of operation of the SZ Gazelle 402 engine. In this case, we are talking about any models of this car - both with a 406 engine and 5-seater Gazelles. The principle of operation of the SZ lies in the accumulation and further conversion of low-voltage voltage into high-voltage voltage using a coil after that. After conversion, the coil transmits and distributes high-voltage voltage to the candles of the system. The candles themselves are used to generate a spark, which, in turn, is necessary to ignite the air-fuel mixture in the cylinders.
The main stages of the work of the SZ:
- accumulation of low-voltage charge;
- converting it to high voltage;
- distribution of momentum on the corresponding candles in a certain order;
- creating a spark on the electrodes of candles;
- combustion of the combustible mixture.
Ignition order
The scheme for connecting the cylinders on the Gazelle, that is, the very order of their activation, for the 406 engine is as follows:
- first, the mixture ignites in the first cylinder;
- then the caviar is served on the third;
- after that - on the fourth cylinder;
- the second cylinder is the last to work.
Basic elements of SZ
Briefly about the main components of the SZ:
- , which includes several coils;
- switching device;
- distribution mechanism;
- candles;
- candle tips;
- elements for connecting candles to a coil - high-voltage cables.
Lock replacement and repair
If nothing happens when you try to turn on the key in the lock, that is, the engine does not start, the problem may lie in the poor connection of the contacts. You can try to repair such a lock, if this does not help, then the device will have to be changed (the author of the video is Sergey Vishnyakov).
Replacing the contact group
Such a task is performed as follows:
- First you need to disconnect the battery, to do this, reset the negative terminal from it. Next, the protective lining of the steering column is dismantled. Using a flat head screwdriver, you will need to remove the two bolts that secure this shroud.
- Having done this, you can dismantle the upper part of the lining.
- Next, the steering column is moved to its highest position. You will need to slightly tilt the top of the trim towards you until the fasteners of this part of the casing come out of the slot.
- Then the lining is dismantled, it must be shifted up.
- Using a flat-tip screwdriver, you will need to unscrew the two bolts that secure the contact part of the lock. Then the contact component is removed and replaced with a new one, further assembly is carried out in the reverse order.

Changing the lock
To completely change the lock, do the following:
- As in the previous case, you first need to dismantle the protective cover.
- It will not be possible to dismantle the clamp, since regular nuts do not have edges, so it must be cut, for example, with a grinder. Be careful not to damage the steering column tube.
- Next, you will need to turn off the steering column - this is done so that the further replacement procedure is more convenient. First, a long screw connected to the steering wheel height adjuster is unscrewed. After that, the steering wheel itself should be lifted up, this will allow you to unscrew another bolt, for this a 12 wrench is used. When removing the screw, you will need to remember the position of the curly brace, it is located next to its cap.
- The next step is to remove the old ignition.
- Now take a new bracket and make slots in its sides where the caps of the lag screws will be located. The slots are a must as they will allow the four lag screws to be tightened without any problems. In the event that there are no slots, this will lead to the fact that the heads on the ratchet will rest against the edges, so that it will not be possible to securely fix the device.
- Next, the device is placed in the seat, four screws are tightened, they need to be tightened to the maximum. The two 12" nuts you removed earlier do not need to be fully tightened as this will result in you being unable to adjust the steering wheel. Assemble the entire structure and test the operation of the installed lock.
GAZ-3302, -2705 - "Gazelles" of the earliest production were equipped with engines of the Zavolzhsky Motor Plant with a capacity of 100 hp. and the Ulyanovsk plant, respectively, 90 hp. The wiring of these models partially differs from models with injection engines in the part where the description of the ignition systems and additional sections of the control sensor circuits are carried out.

Schemes of electrical equipment of cars Gazelle GAZ
I am the owner of a 1998 passenger gazelle. Or another, adhering to the conventional and color designations, you can independently replace the old wires. Accordingly, for example, ZMZ-4061 or ZMZ-4063, the owners prefer a more modern injection engine, which is going to replace the engine with a Gazelle. If the resource of the restored power unit is encouraging, and there is a Gazelle wiring diagram at hand, the 402 engine may well last more than one hundred thousand kilometers. Tip: the Gazelle 402 wiring has color divisions shown, which correspond to the colors. Very often, Gazelle owners, when replacing power units from carburetor versions to injection versions, since there are serious differences in the electrical circuit, are faced with the need to replace the electrical wiring in the car. Leaving in the past the carburetor, and the old tank design is not suitable for this; The new injection engine ZMZ-406 is more demanding on the cooling system, the replacement of the power unit inevitably entails the replacement of the power system: new power unit: Do not forget that the injection engine power system is controlled by an electronic unit. Gazelle 406 wiring diagram: do-it-yourself wiring installation features on this type of motor, differences between a carburetor and an injector, instructions, photos, videos. Accordingly, than on older versions of a car with engines of the 402 series, and is subject to mandatory replacement, the electrical wiring is different for the Gazelle 406. More complex are the interior and engine compartment. The Gazelle, which has become an indispensable vehicle with a 402 engine, still requires attention over the years. The article came in handy, a great helper for my future engine replacement and therefore wiring. The easiest in terms of connection is the back of the car, where you only need to fix the harness and connect the taillights and the fuel level sensor in the gas tank. Tip: Be that as it may, by removing the motor for a bulkhead, the owner has the opportunity to replace the old electrical wiring. I didn’t think much about wiring nuances and differences. On the instrument panel, we power the central head light switch, the emergency gang button, and connect the devices. As a rule, produced before 2001, and having carburetor versions of power units, Gazelle cars require major repairs. That is why it is important to have a visual aid on hand when carrying out such an operation, and not a factory one. The fact is that its performance is being checked, that on newer versions of Gazelles, the scheme for connecting certain devices has also changed: After assembling the wiring into a single whole. Equipped with a ZMZ-402 carburetor engine, and when the time comes for a major overhaul, but also about reconfiguring its operation, many owners think not only about restoration, the car successfully develops its motor resource. Laying the wiring harness is not a difficult matter, the technological holes, that the places for their fastening on the frame, were originally provided for gutters, all the more so. Wiring is not listed among the parts to be scheduled for replacement, however, the electrical circuit is often required when carrying out repair work in the engine compartment. However, a complete replacement is not always justified, since the repair does not affect other electrical devices other than the ignition and fuel injection systems.
Each car is equipped with an electrical diagram, which indicates all the devices and equipment used in the car, as well as the connection circuits. The performance of the wiring is very important for any vehicle, since damage to it can greatly complicate the operation of the car. What elements does the Gazelle electrical circuit include, what malfunctions are typical for it? Find answers to these and other questions below.

General information
The wiring diagram in a GAZ car with a carburetor or injector engine consists of many components.
And it doesn’t matter whether it’s Gazelle 402, 405, 406, 3302, 2705, Business or Euro, the electrical equipment scheme will include the following subsystems:
- Ignition system. This assembly consists of different components, the main ones are the switchgear, candles, and also those that transmit the charge. The functionality of the engine and its operation in principle depend on the performance of this system.
- Optical system. It includes all external headlights, ranging from dimensions to brake lights and fog lights.
- Lighting in the car interior, including on the dashboard.
- Electronic (depending on the car model).
- Wiper system, including an electric motor and.
- Fuel system, one of the main components of which is a pump.
- and generator set.
- Audio system, if available, etc.
How to determine the malfunction?
In the event of a malfunction in the operation of the equipment, first of all, it is necessary to check the integrity of the safety devices. If a short circuit or power surge occurs in the wiring diagram, the safety elements are the first to fail, protecting the main devices and electrical equipment connected to a particular circuit. Since a visual check is far from always effective, troubleshooting should be carried out using a multimeter tester.
The diagnostic procedure consists in removing the fuses from the seats and further checking the sockets. If you have identified a failed fuse, this does not mean that the test can be completed, since a short circuit can occur simultaneously in several circuits (video by Denis Legostaev).
If a short circuit occurs in the wiring of a car with a carburetor or injection engine, then you need to start diagnosing the condition of the circuits. Of course, if all the fuses were intact. Before diagnostics, turn off the mass, you will need a tester or a control light directly for testing. When using a lamp, one of its contacts should be connected to the base, and the other to the center contact.
The check itself goes like this:
- first, the key in the ignition lock should be set to position I;
- then, in turn, connect the probes of the tester or lamp to the contacts in the fuse sockets;
- in the event that the lamp does not light up, this indicates that there are no short circuits in the checked section of the circuit, but if it lights up, then a short circuit has been detected.
Another important point is the diagnostics of the integrity of electrical circuits. In this case, the search principle is quite simple - for diagnostics you will need the same tester (a voltmeter or ohmmeter will do) or a lamp with wires. You will need to connect one of the contacts of the probe to the vehicle body, and use the second contact to measure the power in the connecting places between yourself and the equipment.
It is best to start in the middle of the electrical circuit and check easily accessible places first. In addition, for diagnosing a break, it should be understood that most often the circuit damage occurs at the bends in the wiring. Moreover, as practice shows, wire harnesses are very rarely damaged.
Another breakdown in the electrical circuit is poor contact at the joints, the search for such a malfunction is best done using a tester - a voltmeter.
There are two diagnostic methods:
- One tester probe should be connected to the car body, and the second to the connection terminal, the voltage measurement is carried out in two directions. Please note that the voltage drop should be no more than 0.5 volts.
- The next method is to connect one wire to a pin on one end of the plug and the other wire to a pin on the other side of that plug. In the event that the tester shows more than 0.5 volts, this indicates that the contacts on the plug should be cleaned (the author of the video is the MZS TV channel).
Possible Wiring Problems and Solutions
What malfunctions are most typical for the electrical circuit of Gazelles 4216, 2003, 2705 and other models:
- Wiring damage. If the damage is not serious, then this problem can be solved by additionally insulating the circuit with electrical tape. With more significant damage, the entire chain section is best replaced.
- Failure of the safety element. Malfunctions of such a plan are solved by replacing damaged devices. Never use homemade fuses made from a piece of wire or in the form of a coin, as this may cause a fire. The only time this is possible is when the fuse has failed, without which the car will not start, for example, the one responsible for the fuel pump, and you will only need to drive to the nearest store.
- Poor contact of the equipment with the mains. In this case, you need to make a diagnosis, detailed instructions are presented above. If the poor contact is due to oxidation, then it will be enough to clean the connector, but if the contacts burn out, then they will most likely have to be changed. In this case, please note that you need to determine the reason why the contact burned out.
- Malfunctions in the ignition system. For example, this may be damage to the distributor housing, poor contact of high-voltage wires with the distributor and spark plugs. Also, the car owner may encounter a malfunction of high-voltage, in particular, we are talking about insulation breakdown. Such a malfunction will lead to unstable operation of the power unit as a whole, it can be solved by replacing the wires.
- Failure or incorrect operation of the generator. This node, as you know, is designed to power all the electrical equipment of a car. It consists of many components, most often the brushes wear out, the windings burn out, the voltage relay fails. You also need to monitor the tension of the alternator belt - it should not be overtightened or under-tightened. Damage to the belt is also not allowed - if there is, you need to think about an early replacement.
The electrical circuit of a Gazelle commercial vehicle may differ primarily depending on which one. The wiring is also different according to the type of body - for example, the rear lights are located differently than the onboard one. Accordingly, the wires are laid in a different place, having a different length.
Wiring in the cab of a GAZ 3302 truck
Different generations of cars should also be taken into account by year of manufacture - instrument clusters, optics, fuse box, etc. change over time. Plugs and wiring change in the electrical circuit. Therefore, there are many modifications in the electrical circuit.
Despite many modifications, the principle of building an electrical circuit is the same on all cars. All consumers of electrical energy are powered by a constant voltage of 12 volts. The mass of the body and the power unit is a negative wire, the electrical circuit is two-wire.

Various schemes depending on the engine
The very first to be installed on the Gazelle were ZMZ 402 carburetor engines. For the operation of the internal combustion engine ignition system, it was necessary to supply power to the ignition coil, distributor and switch. The next in the series also went in a carburetor design.
But there was already no coil, distributor and switch on it, instead of them an electronic ignition control unit was installed.
Later, the Gazelle began to be equipped with the ZMZ 405 injection engine, which had a distributed injection system instead of a carburetor.
It looks like the ZMZ 405 engine
The engine wiring on this engine is already completely different - the control unit has become common to both the ignition system and distributed injection.
have their own electrical circuit, and it is different depending on the type of internal combustion engine installed: Cummins or UMZ-A274. The Gazelle Next has been equipped with a new 2.7-liter engine since the end of 2014.
Rearranging the engine wiring
Prudently divided the bundles of wiring into the front, rear and engine compartment. Therefore, when changing the power unit to another type of engine (for example, a ZMZ 406 carburetor to a ZMZ 405 injector), it is not necessary to change all the wiring at all, just change the engine compartment wires. 
It is also easy to rearrange the engine compartment wiring harness in case of replacing the 3M3 402 internal combustion engine with a ZM3 406 carburetor or ZMZ 405 injector.
