UK trailer & tow bar wiring diagram


 

Unfortunately we can not supply wiring diagrams for Vehicles as the manufacturer changes looms & 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  hope you find this wiring diagram useful.
