Hi. I've paid for technical documentation access on the servicebox but after clicking on diagrams only an empty window opens..
Does anyone know how to access electrical diagrams nowadays?
Can anyone help me with identifing lights wires in the rear harness?

Is this for a towbar?
The easiest way is probably just with a test lamp or voltmeter & get someone to operate the lights.

Did you get anywhere with this?
I bought a vehicle specific 13 pin tow bar that I have fitted. Have traced the wires for 7 pin light trailer but haven't managed to isolate the right psa wire to connect to or fog lights. Has anyone managed to get a wiring diagram? I phoned citeoen who said they don't hold this information and suggested going to my local dealer who want to charge for the information......any help much appreciated.
