Wire colors
The following colors of wire are used in basic electrical circuits:
| Red | "+" 12 V to ignition switch |
| Yellow | "+" 12 V after ignition switch |
| Blue | Chain of marker lights or identification devices |
| Black | Direct connection to "mass" |
Other colored wires are also used for other circuits and connectors.
| VA | White |
| BE | Blue |
| BJ | Beige |
| CY | Transparent or white |
| GR | Grey |
| JA | Yellow |
| MA | Brown |
| NO | Black |
| OR | Orange |
| RG | Red |
| SA | Pink |
| VE | Green |
Note: Starter + circuits, ground connections, and polarity reversal circuits are not considered to be main electrical circuits. Presence or absence of circuit protection devices (fusible and bimetallic fuses) does not affect the applicability of electrical wires.
The colour coding of electrical wires on electrical equipment supplied as spare parts does not always comply with the above rules.
Designations adopted on electrical diagrams
| 1 | Connector color |
| 2 | Connector diagram |
| 3 | Connection diagram |
| 4 | Connector color |
| 5 | The number of the board to which the device is connected |
| 6 | Device number |
| 7 | Nominal current of the fuse |
| 8 | Location of the fuse on the board |
| 9 | Holder color |
| 10 | Connection number |
| 11 | Wire splice location number |
| 12 | Connection number with "mass" |
| 13 | Auxiliary element |
| 14 | Connection diagram |
| 15 | Target code (allows you to determine the purpose of the wire), see list of chains |
Note. Auxiliary element: this is an element that supplies information to the ECU, based on which a control signal is issued to the relay. More detailed connections between elements and the ECU are shown in the corresponding diagram.
