Locate behind the instrument panel the bundle with pink colored spare
wires. Take the pink/blue (Ro-B) and pink/yellow (Ro-Ge) spare wires
apart.
Locate in junction box EKV the other end of the pink/blue (Ro-B) and
pink/yellow (Ro-GE) spare wires. Due to the presence of multiple
identical colored spare wires in EKV, a multimeter must be used to find
the proper end.

At the back of master switch S068/S080: disconnect the connector socket.
By using terminal removal tool VH10541368, remove connector terminal of
contact number 6. Cut off the cable terminal and isolate the wire end with a
heat shrink tubing because this wire will not be reconnected.

NOTE: The indicated pink/yellow (Ro-GE) spare wire routes between the
dashboard and junction box EKV.
Route the pink/yellow (Ro-GE) wire from the spare wire bundle to the
connector socket of S068/S080. Strip back the wire and crimp female
connector terminal 10616407 from the kit to this wire. Introduce the connector
terminal into contact number 6 of switch S068/S080 connector socket.
Change instrument panel wiring as follows:
a. Locate the black connector.
b. Unlock the connector by pushing the tab (1) and turning the locking lever
(2) of the housing upwards.
c. Remove the connector.
d. Slide the connector with the colored wires out of the housing.
e. Remove the connector terminal of contact number 36 by using a small flat
screwdriver
f. Cut off the connector terminal and isolate the wire end with a heat shrink
tubing because this wire will not be reconnected.
