Connecting the power supply
Depending on the vehicle type (with or without RDU fuse holder (Fig. 3/2) at the rear), power
must be connected as follows.

Power is picked up from the RDU at the rear.
17. Lay the red cable to the RDU (Fig. 3/2) under the left-hand tail light.
18. Cut the cable to size and crimp the supplied small socket contact (Fig. 3/1) onto the cable
end.
19. Dismount the RDU and insert the socket contact of the red cable from below into position 7
(fuse F75). Then reassemble the RDU.
20. Insert a 15A minifuse into position 7 of the fuse holder.
Version B (without RDU fuse holder):
Power is picked up directly from the constant plus (+30) of the battery.
21. Lay the red cable on the left side along the vehicle's cable harness to the front into the engine
compartment. Lay the cable as shown in the vehicle drawing (Fig. 1 and 2).
22. Push the cable through the cable leadthrough (small leadthrough) under the rod system of the
windscreen wiper (Fig. 1/3, 2/3). Make sure that the cable is securely fastened.
23. Crimp the supplied large contact onto the cable end.
24. Let the quick-connect receptacle of the red cable of the cable harness and the individual red

distributor (Fig. 2/1).

Note: If the vehicle is not equipped with a PDC system, insulate the brown/white cable and
secure it properly.
