Hi chaps , I'm installing a Prodigy P2, what wire in the foot brake switch is the COLD one please? , also what is the brake wire that goes through to the trailer plug ? or do I run a separate wire to the rear ?

And do read it all - the recommended wiring method changes over the 100 or so posts in the sticky. Sniegy starts with the LR recommended way, but this gets AULRO improved along the way.

Any questions, just reply to the sticky to keep building on the knowledge base.
