Electrical circuit number
Applied to make it easier to locate connections.
Conventional designations
In all diagrams the same designation is used for each element.
As an example, we provide a fragment of one of the electrical circuits (figure 470), where:
- F60 - Idle switch
- N114 - ignition delay control valve
- T6a - six-pin plug connection
- U60 - idle speed control motor
- 117, 126 - ground connection points at the idle switch
Table 27 provides information on which electrical circuits are used on certain car models depending on the power of their engines.
Table 27. Location of electrical circuits depending on the vehicle engine model
| Engine, power | Designation | Electrical circuit |
| 1.6/53, 55 kW | EZ, RF from 8.89 | 1-17 |
| 1.8/66 kW | GU from 8.89 | 1-17 |
| 1.6/51 kW | PN from 8.89 | 1-2, 5-17 |
| 1.8/66 kW | RP from 8.89 | 18-20 |
| 1.8/82 kW | RV from 8.90 | 21-23 |
The field at the top of the diagram may be "filled" with gray color, it displays the internal diagram of the mounting block. Lines with designations "30", "15", "X", "31", etc. correspond to the terminals of the ignition switch or instruments and the starter. The numbers placed in a square frame on a black background and placed next to the control units and relays correspond to the number of the device field in the mounting block. Wire breaks indicate the wire cross-section in mm²; the digital designations in the square frame at the end of the wire correspond to the number of the route along which the wire is laid.
The connection points with the "ground" are indicated by numbers in circles: (30), (119).
