The number is unique except for:
^
15 = +15 voltage
^
30 = +30 voltage

54 = +54 voltage
Leads with the same letter and number, e.g. E110, E110-1, E110-2, etc., normally belong to the same function.
Colour code
The following colour codes are used in wiring diagrams. The colour codes can also be used in combination, e.g. RD/BU, GY/WH. The cables then have
at least two colour fields of each colour.
Cross-sectional area
The cross-sectional area of the conductor is specified in sq.mm and determines the current the cable is capable of carrying.
Thermal stability
Cables used in the front harness and engine harness have a higher temperature resistance. When replacing the cables in these harnesses, cables with the
new type of insulation must be used.
