Every modern car today is equipped with an electrical part. The electrical diagram of the VAZ 21214 Niva injector allows, if necessary, to find all the elements enclosed in the on-board network, which is especially important when faults in the wiring appear. Everything that the nivovod needs to know about electrics in domestic SUVs is described in this article.

Niva index designations
The wiring diagram may vary slightly depending on the design features of the vehicle.
First, consider 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 implies 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 injectors or a Solex carburetor ICE. One of the features of these cars is the contactless ignition circuit.
- 21215. These SUVs were originally produced for export, so these cars are hard 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 the difference in the circuit diagram will be, but not fundamental. If we are talking about carburetor engines, then in this case the circuit, as well as the ignition, will not be protected (video author - Nail Poroshin).
Features of electrical equipment
The wiring diagram of the VAZ model 21213 has certain differences from the model 2121, in particular:
- On 21213 cars, the fuse block uses more modernized leg fuses. Of course, the use of such devices led to the fact that the block site also changed.
- The power supply system of these vehicles additionally includes an idle speed saving device. For this option to work properly, another wiring connector has been added in the engine compartment.
- Another difference is that these cars use a contactless ignition circuit, the main element of which is a microcontroller.
It should be noted that the differences in the Niva circuit can lie both in the generating units and in the electrics itself.
Differences in generators
In any case, the differences in the wiring diagram of the models will be primarily depending on the power unit - carburetor or injection.
The main differences in carburetors:
- models 21213 uses Model 371.3701 Generator Assembly;
- in engines of models 21214, the manufacturer decided to install a more powerful generator device, it is marked with the numbers 9412.3701 (video by Sergei Chekhonin).
And although these generators are different, they have certain structural similarities. In any case, it is an AC synchronous device. In addition, these units have a built-in rectifier and an output voltage regulating mechanism.
Differences in wiring
If we talk directly about the wiring, then depending on the car model, it may also differ. It should be noted that these differences greatly simplify the maintenance and repair of the system with your own hands. As for the injection modifications of SUVs, in this case, the system is equipped with three outputs designed for installing electronic ignition.
In addition, 21214 vehicles use two ventilation devices that perform the function of cooling the radiator assembly. Accordingly, due to the use of additional fans, the wiring also underwent, if not significant, but differences. Of course, they are not fundamental.

Summarizing
The need to understand the wiring diagram may arise if there are malfunctions in the system and 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 garage conditions without certain knowledge. Nevertheless, even a 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 the wiring may also arise if you decide to upgrade your acoustics or install a more advanced audio system.

Fuse box VAZ 21213
Much has been written about how timely the first domestic SUV with a monocoque body was. Even more was expressed by the owners of the Niva car themselves, who practically deified its capabilities. All they needed for operation was the availability of spare parts and instructions for servicing the vehicle.
What do the numbers in the Niva index mean
The only thing the owners complained about was the lack of power of the car, which did not allow it to realize its full road potential. That was why there were objective technical difficulties associated with a shortage of production capacity, which the automaker eventually managed to overcome.
In the video at the end of the article, you can see how the release of the 2 millionth car was celebrated, which confirms the high consumer demand. In a word, the developers did not remain deaf to modern trends, proposing several modifications of power units for the VAZ 2121 "Niva" car at once.
| Engine capacity | Injection system | Ignition system | Power, h.p. | Factory index |
| 1.6 l | carburetor | classic | 79 | VAZ-21210 |
| 1.7 l | carburetor | classic | 80 | VAZ 21213-1000260 |
| 1.8 l | carburetor 21073 "Solex" type or injector | contactless / injection - electronic with Bosch MP 7.0 controller | 82/85 | VAZ 2130-00 - carburetor VAZ 2130-20 (26) - injection |
| 1.7 l | distributed fuel injection | contactless with the BOSCH MP controller 7.9.7. or JANUARY 7.2 | 83 | VAZ-21214-20 |
| 1.9 l | diesel XUD-9SD | — | — | VAZ-21215 |
For reference: The code on the VAZ 21213 and VAZ 21214 block always begins and ends with a * (asterisk). Therefore, the block marking for the indicated models consists of ten characters.
Accordingly, the cars themselves received new indices linked to the installed power unit:
- A 1.7-liter carburetor engine with a classic carburetor is designated in the documentation as VAZ-21213;
- An engine of a similar volume with distributed fuel injection - VAZ-21214;
- The VAZ-2130 carburetor engine with a volume of 1.8 liters also had the VAZ-21213 index;
- The VAZ-21215 index is used for export models equipped with a Peugeot-Citroen diesel power unit.
For reference: In Russia and the CIS countries, a car with a diesel engine was not officially sold. The price of the SUV was higher than the passenger car models, but this did not stop buyers seeking freedom of movement.
The photo below shows the wiring diagram of a VAZ 21213 with a classic carburetor power unit. 
Note! The applied wiring diagram of the Niva VAZ 21213 differs from other modifications. In particular, on the carburetor model, the battery charging and ignition circuits are not protected.
Features of electrical equipment
Differences in generators
It has already been mentioned that the wiring diagram of the VAZ 21213 had some differences, primarily associated with the installed power unit.
In particular, the fuel-injected versions required a more powerful generator, so:
- A model 371.3701 generator was installed on the VAZ 21213;
- The VAZ 21214 was equipped with a generator model 9412.3701.
They are structurally similar and are synchronous AC machines with built-in rectifier and output voltage regulator. 
Differences in wiring
The engine compartment wiring of the VAZ 21213 is made in a different design to facilitate do-it-yourself maintenance. 
For versions with an injection power unit, the wiring on the VAZ 21213 has three additional connectors for the contactless ignition unit.
In addition, on the VAZ 21214 model there are 2 cooling fan radiators, respectively, the wiring for them also has its own differences from the "thirteenth" one. A schematic diagram of connecting the elements of the cooling system is presented below.
Finally
The name of the car "Niva" speaks for itself. And the love of car owners ensures long years of its operation. And we hope that the proposed schemes will help in this.... Good luck on the road!
