Explanations for electrical diagrams

Most electrical appliances are connected to «weight» brown wires. For correct connection, the contacts of the electrical equipment are numbered. For ease of use, all electrical circuits on the wiring diagrams are arranged vertically and numbered.

The diagrams above show the central control unit. Thin lines show internal connections in electrical equipment.

At the bottom of the diagrams there is a horizontal line that shows the connection to «weight».

Circled numbers near the intersection of vertical chains with a horizontal line «masses», indicate the location of points «masses» on the body.

The number in the white square at the end of the vertical chain indicates in which chain you need to look for the continuation of this wire. The number on each wire means the cross-sectional area of the conductive core of the wire in mm².

The number in the black square indicates the number of the relay in the relay box. A letter with a number or a number in a circle next to a wire indicates a permanent connection in the wiring harness.

Numbers under the bottom line «masses» show the circuit number.

Attention! All switches and contacts in the diagrams are shown in their original condition.
