Wiring Diagram Type 928 S4/GT

Model 91

The wiring diagram comprises of and 1 sheet plug connections, ground points, M-numbers and abbreviations. They are subdivided into coordinate fields.

Each individual wiring diagram comprises a part of the central-electrical system within a dash-dot

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 pans

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

11 15,

to the “initial element”, from A
