Wiring Diagram Type 928 GTS
Model 93
The wiring diagram comprises of 12 individual wiring diagrams, 1 sheet construction components
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 “GP” 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”.
Parts 2, is the “module element”.
Both parts are identified by the digits 1.....S.
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 ii....... 15, to the “initial element”, from A 21......25 to module element.
