Lighting diagram

Looking to wire up a tow bar to my C3 2002 model but need wiring diagram to identify correct wires.

Anyone got a link to a good schematic?

Cheers also the tow bar is new but bought second hand ( no fitting instructions ) it has a 7 pin plug. Are the wires that go to the car lights normally wired into the plug universal IE. stop light say pin 1? the wire for the tow bar to lights just consists of one length of wire with a small box to sound when indicators are turned on off.

Ie been told that the C3 wiring for tow bars can be problematic and can damage the ECU if wired incorrectly is this true If so it's important that the schematic is a good one.

Cheers for any and all advice

Haynes is good for this, see this one on Amazon.

If you mess up the wiring you can damage the BSI or BSM and your expensive journey begins
