Electrical Wiring Diagrams — General Characteristics (Opel Vectra A)

1. The wiring diagrams are shown in a simplified version. Please note that the original diagrams were developed in Germany and all wire colors and abbreviations are indicated in German.

2. Below the bottom mass line on the diagrams there are coordinate numbers by which you can use the key to find a specific circuit or component.

3. The power lines at the top of the diagram are positive connections. Line "30" has power all the time, and line "15" only has power when the ignition is on.

4. The numbers on the diagram in the square boxes at the end of the wire show the coordinate number at which it continues. And at this point there is a return link.
