Niva index designations
Detailed electrical diagram of Niva
The wiring diagram may vary slightly depending on the design features of the vehicle.
First, let's look at the index notation:
- VAZ 21213. This index designates a vehicle equipped with a carburetor. The volume of the power unit is 1.7 liters.
- 21214. In VAZ 21214 cars, the scheme involves the use of a similar engine with the same volume. The only difference is that the car is equipped with a fuel injection system.
- There is another model with the index 21213. In VAZ 21213 cars, the electrical circuit includes the same elements, only depending on the year of manufacture, the car can be equipped with a 1.8 liter engine.
- Version 21073. The SUV is equipped with either an injection engine with nozzles or a Solex carburetor engine. One of the features of these cars is a contactless ignition circuit.
- 21215. These SUVs were originally produced for export, so these cars are difficult to find on our roads. It is worth noting that they were equipped with Citroen diesel engines.
At the beginning of the article there is a diagram of the VAZ electrical equipment using the example of the Niva 2121 model. If you are the owner of version 2131 or any other, then there will be a difference in the circuit diagram, but not fundamentally. If we are talking about carburetor engines, then in this case the battery charging circuit, as well as the ignition, will not be protected (video author - Nail Poroshin).
What do the numbers in the Niva index mean?
To understand the features of the wiring and electrical equipment of a Niva 2131 car or another model with an injector or carburetor, let’s look at the index designations:
- VAZ 21213 - this is how a Niva with a carburetor is designated. In this case, the engine volume is 1.7 liters.
- VAZ 21214 is the same carburetor with the same engine size. Only in this case the car is characterized by a distributed fuel injection system.
- VAZ 21213 is also a carburetor, only Niva with such digital designations can have a 1.8-liter engine.
- VAZ 21073. This Niva can be equipped with either a Solex carburetor or an injector. The ignition system in these cars is contactless.
- As for the Niva 21215 models, this index designates export versions of vehicles equipped with a diesel engine from the manufacturer Citroen.
Features of electrical equipment
The electrical circuit of the VAZ model 21213 has certain differences with the model 2121, in particular:
- 21213 vehicles use more modernized foot fuses in the fuse box. Of course, the use of such devices led to the fact that the block site also became different.
- The power supply system of these vehicles additionally includes an idle speed saving device. For this option to work properly, another connector with wiring was added in the engine compartment.
- Another difference is that these cars use a non-contact ignition circuit, the main element of which is a microcontroller.
It should be noted that differences in the Niva circuit may lie both in the generator units and in the electrics themselves.
Differences in generators
In any case, the differences in the wiring diagram of the models will primarily depend on the power unit - carburetor or injection.
The main differences in carburetors:
- models 21213 use the generator unit model 371.3701;
- in the engines of models 21214, the manufacturer decided to install a more powerful generator device; it is marked with the numbers 9412.3701 (video author - Sergei Chekhonin).
And although these generators are different, they have certain similarities in design. In any case, it is a synchronous AC device. In addition, these units have a built-in rectifier and output voltage regulation mechanism.
Wiring differences
If we talk directly about wiring, then depending on the car model, it may also have differences. It should be noted that these differences greatly simplify do-it-yourself maintenance and repair of the system. As for injection modifications of SUVs specifically, in this case the system is equipped with three outputs intended for installing electronic ignition.
In addition, 21214 cars use two ventilating devices that perform the function of cooling the radiator assembly. Accordingly, due to the use of additional fans, the wiring also underwent, albeit not significant, differences. Of course, they are not fundamental.

Summarizing
The need to understand the wiring diagram may arise if there are malfunctions in the operation of the system and they need to be eliminated. Of course, complex malfunctions associated with the operation of the generator unit and other devices that are not simple in terms of design will be problematic to solve in a garage without certain knowledge. However, even simple knowledge of the electrical circuit and the ability to decipher the symbols can greatly help the car enthusiast during repairs. In addition, the need to understand wiring may also arise if you decide to upgrade your speakers or install a more advanced audio system.

Since 2004, the car was renamed from NIVA to LADA 4x4
Since 2013, daytime running lights began to be used: a 2-filament lamp is installed at the side lights in the side light section. When the ignition is turned on, the power comes to the 21W thread (running lights mode), when the external lighting is turned on, the power switches to the 5W thread (side lights mode).
