I have a witter towbar, with a PF Jones 12N wiring harness.
I have bought a new trailer, with brakes, has a 12N +12S sockets - presumably for the reverse lights, but i also have plans for stuff on the trailer.

So, i need to add a 12S socket. (or a 13pin euro) to the car.

does anyone know of a supplier of a ready to plug in harness?
(pf jones only do the 12N)

alternatively, anyone have a copy of the pinouts for the socketin the boot of the car so i can make up a harness ?

or...
will i have to take a feed from the reverse lamp on the car; and will i need a relay bypass?

i plan to add a dc-dc charger and an auxiliary battery: either in the car, or in the trailer.
