Electronic Brake Controller Wiring Question
I am wiring a brake controller for my trailer brakes. It instructed me to connect to the cold side of the brake switch, which I interpreted to mean 12 volts when the brakes are on. One of the four wires did indeed give 12 volts when the brakes/ignition were on so I chose that one. Driving around tonight my brake controller randomly came on as if I were hitting the brakes when I actually wasn't. Additionally I can hear a factory relay under the dash clicking when I hit the override braking button on my controller (which shouldn't be happening).
Has anyone hooked up a brake controller and if so which wire did you use? Thanks |
I recently put a Tekonsha P3 in my Disco. I connected Red controller wire to the Green/Purple brake wire.
This is for my Disco Vehicle side of 7Pin Trailer Socket: (second colour is trace) Black - Ground Red/Orange - RH Tail Green/Purple - Stop Lights Green/White - RH Indicator Green/Red - LH Indicator Red/Yellow - Rear Fog Red/Black - LH Tail Single Pin Socket A: Green/Brown - Reversing light Single Pin Socket B: 20A fuse F6 in Satellite 2 (I think) Purple/Brown - Power |
