We often receive requests for trailer and tow bar socket wiring diagrams.

This is a wiring diagram for a 12n, 7 pin standard trailer socket, it also covers the wiring of any UK trailer and most European standard 12n wiring.

Unfortunately we can not supply actual vehicle wiring diagrams as the manufacturer changes looms & wire colours on a regular basis & it is impossible to keep up with them. It is just a case of testing for feeds prior to connecting the trailer wire in to your vehicle loom.

We trust you find this wiring diagram useful.
