Note: Due to the variety of configuration options for the vehicles in question, only some of the most typical electrical equipment diagrams are provided below. For more detailed information, please contact your Opel service station.
The most important terminals
Terminal 15 (Ignition switch "ON" position). Receives power through the ignition switch. The wires only supply power when the ignition is on and are usually green or black with a stripe of another color.
Terminal 30 ("+" battery) Power from the battery is supplied to this terminal; is usually red or red with a stripe of another color. Terminal 31 (battery "-") Leads to ground. The wires are usually brown.
Electrical wiring designation
The designation of wires on the diagrams is of the type BKWH 0.5
The numbers (0.5) indicate 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 (if available) wires - the second two letters:
- VK - Black
- BR - Brown
- BU - Blue
- GN - Green
- GY - Grey
- OG - Orange
- RK - Pink
- RD - Red
- VT - Violet
- WH - White
