I'm assuming if everything still wired up correctly, it would be safer to swap the wires on the van than the car

Thanks again

Thanks for your replies, the car was supposedly fitted with a vehicle specific wiring kit which gave me the impression is was just a plug in affair. So I'll work on the basis that its the caravan thats wrong, although other people who have towed it haven't reported a problem. But I guess its not something you tend to look for, more that they are just working ok when checking the lights before setting off.

The plug in wiring kits plug in at the light clusters usually, so this end will certainly be correct. The other end that connects to the 12N socket comes a bare wires as it has to be passed through the vehicle body before connecting to the socket, so it is quite possible the wires could be incorrect in the socket.

I had a rear end shunt a few years ago and the car came back from the repairers with the towbar electrics reversed.

Fix a set of wheels on roof and tow it upside down.
