Current Flow Diagram 97-233

Wiring Diagram Type 928 S Model 86

The wiring diagram comprises nine individual wiring diagrams.

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

individual wiring diagram.

The ground-connecting points are designated with “MP” and their location is

shown in a vehicle diagram.

The IO- pole plugs on central electrical system are clipped together

from 3 parts.

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

Part 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 wiring diagram for central electrical

system refer e. g. from A 11 . . . 15 to the “initial element”, from A 21 . . . 26 to

module element.
