I have just fitted a towbar and I am now starting on the electrics!!!!! I have bought a 7 way bypass relay, and I have found the Audi's wire colours for the various circuits I need to tap into.....my question is....Is there a socket somewhere within the hindquarters of the car that provides these wires all in the same place, and if so, where is it?
The Audi current flow diagrams show a connector designated U10 I think that is the connector I am looking for, but it may be that U10 is the actual trailer socket that the trailer plugs into that is fitted to the tow bar! Does anyone know? I could then just connect all the bypass relay wires to that connector and then connect the bypass relay terminals to the trailer socket....well that's the plan anyway....
Recent info...U10 is indeed the trailer socket that the trailer plugs into and not a socket inside the car. I have looked behind the nearside loadspace panel and found looms containing wires I could use, I have not removed the offside trim yet, but surely Audi technicians are not expected to break into the loom and connect to the relevant wires! Audi must do a loom that goes between U10 and the car!!!!!!! Audi's circuits show wire colours dedicated to the relevant circuits arriving at the back of the trailer socket U10 and going off to various points in the cars circuitry, so we are not talking about a bit of 7 way trailer cable from Towshure!
