The schemes are given in the simplest version. Since they are made in Germany (according to DIN standard), all colors and abbreviations are in German.
The bottom line of each circuit is the negative wire grounded to ground; the numbers below the line help you locate the components using the key.
The lines at the top of the diagram represent live wire (positive). line numbered "30" represents a wire that is always energized, and the wire numbered "15" is energized only after the ignition is switched on.
Diagram numbers given in a square box at the end of a wire indicate the reference number of the direction in which the wire continues. At the continuation point there is another number in the box, being the key to the previous scheme (chains).
