right front bulkhead grommet near the electrics box and then through the grommet (16) into the engine compart-
ment. Lay branches K1to K3along the vehicle wiring harness on the inside wing towards the front and to the
engine near the washer water tank.
The right front bulkhead grommet does not have an additional passage hole for retrofit wiring harnesses in
the first cars in the series. In this case the cables K1to K3are to be laid along vehicle wiring harness through the
front bulkhead grommet.
K
Lay branches K1to K3parallel to the cables for the ABS sensor into the wheel arch and connect them to the
black 6-pin plug X10275 (K) as follows:

Seal slots 1, 4 and 5 with the blind grommets supplied.
Cars with air suspension on both axles only:
Two black/white and two black/grey cables are used. it is therefore essential to keep to the order described to
avoid confusion.
There is already a black 6-pin plug X10275 in the car. Disconnect the three cables (black/brown, black/grey and
black/white) from these plugs and connect them to the black 6-pin plug X10275 (K) supplied in the parts kit as
follows:
Connect the black/brown cable for the air suspension to slot 1 of the black 6-pin plug X10275 (K).
Connect the black/grey cable for the air suspension to slot 4 of the black 6-pin plug X10275 (K).
Connect the black/white cable for the air suspension to slot 5 of the black 6-pin plug X10275 (K).
Connect the cables on the xenon wiring harness as follows:
Connect branch K1, black/white cable, to slot 2 of the black 6-pin plug X10275 (K).
Connect branch K2, black/white cable, to slot 3 of the black 6-pin plug X10275 (K).
Connect branch K3, black/white cable, to slot 6 of the black 6-pin plug X10275 (K).
All cars:
Connect the black 6-pin plug X10275 (K) to the level sensor at the front right (17) and secure the wiring harness to
the hole in the axle with a cable tie (18).
Check again that the entire xenon wiring harness has been installed in such a way that none of the cables
are kinked or damaged and that it has been secured with the cable ties so that it does not interfere with any other
components.
