Wiring Diagram Type 928 S Model 89

The wiring diagram comprises of 11 individual wiring diagrams and 1 sheet construction components, plug connections and ground points. They are subdivided into coordinate fields.

Each individual wiring diagram comprises a part of the central-electrical system within a dashdot frame.

This part of the central-electrical system shows all the lines and relays required for the individual wiring diagram.

The ground-connecting points are designated with “MP” and their location is shown in a vehicle diagram.

The lo-pole plugs on central electrical system are clipped together from 3 parts.

Part 1, with the cast-on fastening pin, is the “initial element”.

Parts 2, is the “module element”.

Both parts are identified by the digits 1......5.

Part 3 is a “coding element”.

The designations of the plug connections in the wiring diagram for central electrical system refer e.g. from A 1 l....... 15, to the “initial element”, from A 21......25 to module element.
