3.5.1 To lay additional wiring harnesses
The installation of the speaker wiring harness
IV
and the switch module
V
is not necessary on cars with a
BMW Professional DSP hi-fi system.The installation of the power supply wiring harness
II
is not necessary on cars
with a 12-pin white telephone SA plug X400. On cars with an existing speaker wiring harness on the socket casing
of plug connector X322, there is no need to install the speaker wiring harness
IV.
On cars with blind stoppers in
the socket casing of plug connector X322, these must be removed.
Connection cable I:
Lay this cable from SA plug X400 and the base interface in the boot on the left-hand side, along the vehicle wiring
harness to the armrest in the centre console.
Power supply wiring harness II (cars without telephone SA plug X400 only):
Lay this from the white plug connector X322 in the boot on the left-hand side, along the vehicle wiring harness to
the fuse holder IV X10018 and to the plug connector X325 in the boot and to the ground post X13075 at the
C pillar on the right-hand side.
Microphone wiring harness III:
Secure the microphone wiring harness
III
so that no deterioration in function occurs on cars with an ITS
head airbag.
Lay this wiring harness from the base interface on the left-hand side wheel arch along the vehicle wiring harness
to the left-hand C pillar and under the roof liner to the installation site of the microphone near the front interior light.
Speaker wiring harness IV (cars without a BMW Professional DSP hi-fi system only):
Before installing the speaker wiring harness
IV
, check the 12-pin socket casing X322 in the boot on the
left-hand side to find whether the following slots are occupied:
Cable colour Slot
white/brown 8
black/white 9
black/brown 10
If these slots (8, 9 and 10) are occupied, the speaker wiring harness is not to be installed. If the socket contact on
slot No. 8 (mute cable) does not exist, press in branch IV/3 and lay branch
IV/6
to the installation site for the radio.
If there is a socket contact on the 12-pole socket casing, insulate branches
IV/3
and
IV/6
and tie them back on
the wiring harness.
LHD cars without existing speaker wiring harness:
Lay the wiring harness from plug connector X322 along the vehicle wiring harness to the A pillar on the left-hand side.
RHD cars without existing speaker wiring harness:
Lay the wiring harness from plug connector X322 along the vehicle wiring harness to the A pillar on the right-hand
side.
