Hi, I was hoping someone could direct me to a simple "Dummys Guide" to wiring a 12s plug to my Disco (200tdi). I already have the 12v normal wiring for towing set up its just I bought a 12s kit a while ago and lost the wiring instructions, it has a relay there to be fitted somewhere. I need one of those simple diagrams, you know the ones ( dead easy to follow )
