10. To install the basic wiring harness A and power supply wiring harness B in E39/2 cars
0Carefully cut open the sheathing of the audio
wiring harness (20) for a length of 100 mm behind
the black plug connector X322.
Connect branch B2, open cable end, grey/red
cable, to the supply cable, grey/red cable, of the
black 12-pin plug connector X322 PIN5 using a
2-way insulation-piercing connector (1).
0Lay branch B3 and branch B4 on the power supply
wiring harness B along the standard wiring
harness (20) to the tied back black 2-pin plug
connector X325 above the power distributor in the
boot on the right.
Secure the power supply wiring harness B to the
standard wiring harness (20) using cable ties (3).
0Connect branch B3, black 2-pin socket casing
on the power supply wiring harness B to the black
2-pin plug casing X325S.
Connect branch B4, black 2-pin plug casing on
the power supply wiring harness B to the black
2-pin socket casing X325B.
0Tie back plug connectors X325S+B3 and
X325B+B4 on the standard wiring harness (20)
with cable ties.
When securing the connections, make sure
that the cable harnesses will not be damaged

Lay branch A9, black 12-pin plug casing, branch
A10, socket contact, white/brown cable, and
branch A15, socket contact, white/green cable, on
the basic wiring harness A to the installation site of
the on-board monitor radio.
0Cars with an on-board monitor radio only
Disconnect the black 12-pin plug casing X13598
from the radio connection plug (20) and tie it back.
Connect branch A9, black 12-pin plug casing, into
the cleared slot (21) in the on-board monitor radio
connection plug (20).
If the car does not have a black 12-pin plug
casing X13598, branch A9 must be
