Wiring Diagram Type 928 S Model 88
The wiring diagram comprises 12 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 1O-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.
