Note: Due to the variety of configuration options for the vehicles under consideration, only some of the most typical electrical equipment diagrams are given below. For more information, contact an Opel workshop.
Most important terminals
Terminal 15 (Position «ON» ignition switch). Receives power through the ignition switch. The wires only supply power when the ignition is on and in most cases are green or black with a stripe of a different color.
Terminal 30 («+» batteries) This terminal supplies battery power; it is in most cases red or red with a stripe of another color. Terminal 31 («-» batteries) Leads to mass. Wires are usually brown.
Wiring designation
The designation of the wires in the diagrams is of the type BKWH 0.5
Numbers (0.5) mean the cross section of the wire (mm2). The letter part indicates the main color of the wire - the first two letters, and the color of the stripes (in the presence of) wires - two second letters:
- VC - Black
- BR - Brown
- BU - blue
- GN - Green
- GY - Grey
- OG - Orange
- RK - Pink
- RD - Red
- VT - Violet
- WH - White
- YE - Yellow
