Thanks for diagram. Yes have regulator which was easy to wire up. Just panicked when seen amount of wires in car harness which were multiples of the same colours.

Tow bar fitted, think it was the last available one in the UK with the time and hassle trying to find one, anyway need help with wiring caravan 7pin into car’s harness in the boot. Found harness quickly but then hit a brick wall. It say yellow to yellow and blue to blue ect. But there are at least 40+ wires in harness, all of each have at least 5 of the same colours. Can someone please advise me on which yellow, blue, black, gray, green ect to tap into. 😳
