The wiring diagram consi~"W ot 1~)ndividual wiring diagrams. These are divided into
coordinate fields. ·
·• · ""'
d
Each
dinfdividual wir~ng diaQ[8.rp cov;~tns a part of the central-electrics box in a dash-
one rame.
This part
of the central-electrlcs.bQx shows all the lines and relays necessary for the
individual wiring diagram. · '·· 3 ·. • •
The earth/ground point$ are .i~~ntified by "MP" and their location is shown in a
vehicle diagram.
"· ·
The 20-pin connectors
pn the c~n~r;al-electrics box are clipped together
out of 5 parts. ··
Part 1, with the moulded-on fasteni':'g lug, is the "starting element".
Parts 2, 3 and 4 are
"mo~ule elemEFpts".
Parts 1 to 4 are identified by tlle ... Q"'·"?bers 1 ..... 5.
Part 5
is a "coding element'~.
The designations of the plug connections in thewiring diagram of the central-electrics
box refer to the "starting element" from, for example, B 11 ..... 15, and to the first
module element from B
