Wire colors
In the main electrical circuits, wires with insulation of the following colors are used:
Red | "+" 12 V before ignition switch |
Yellow | "+" 12 V after ignition switch |
Blue | Chain of parking lights or identification devices |
Black | Direct Ground |
For other circuits and connectors, wires with insulation of other colors are also used: white, blue, beige, gray, yellow, black, orange, red, pink, green, purple, as well as wires with transparent insulation. In the diagrams, they are indicated by the following abbreviations:
VA | White | MA | Brown |
BE | Blue | N0 | Black |
BJ | Beige | OR | Orange |
SU | Transparent or white | RG | Red |
SA | Pink | ||
GR | Grey | VE | Green |
JA | Yellow | VI | Violet |
chains "+" starter, interleaved connections with "weight", polarity reversal circuits do not belong to the main electrical circuits. Presence or absence of circuit protection devices (fuses and bimetal fuses) do not affect the applicability of electrical wires.
The color of the insulation of electrical wires on electrical equipment supplied as spare parts does not comply with the above rules in all cases.
