Wire colors
The main electrical circuits use wires of the following colors:
Red | «+» 12 V before ignition switch |
Yellow | «+» 12 V after ignition switch |
Blue | Chain of parking lights or identification devices |
Black | Direct connection to «mass» |
For other circuits and connectors, wires of other colors are also used.
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. chains «+» starter, 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) does not affect the applicability of electrical wires.
The colors of electrical wires on electrical equipment supplied as spare parts do not comply with the above rules in all cases.
