DESCRIPTION OF OPERATION
All cars are electrically prepared for the fitting of a towbar. For this purpose, 8-pin connector 258 (H8-5) is installed in the luggage compartment on the left-hand side under the left-hand rear light.

Current is supplied via connector 258 (H8-5) to the following lights on the trailer:
Pin 1 Brake lights 30 (from brake lights switch 29).
Pin 2 Rear light 14, right-hand side, and number plate lighting 15 (from lights switch 10 and fuse 29).
Pin 3 Direction indicators 28, right-hand side (from flasher relay 23).
Pin 4 Direction indicators 27, left-hand side (from flasher relay 23).
Pin 5 and 8 Rear fog light 33 (from rear fog lights switch 161).
Pin 6 Rear light 14, left-hand side (from lights switch 10 and fuse 30).

The grounding cable from the towbar's electrical connector must be connected to rear grounding point G3 on the car, using a separate ring cable terminal.

FAULT DIAGNOSIS HINTS
1. Check the electrical connections of the towbar connector, particularly for corrosion.
2. Check that current is supplied to all terminals in connector 258 (H8-5).
3. Inspect the fuses and wiring harness.
