Well I tried searching this topic but still need some help. I have an '06 HSE and it includes the factory supplied wiring. So I connect the trailer up and all the lights work but brakes do not activate. Dealer seems kind of clueless. So: Where is the best place to buy the controller? Anyone know of a good installer in greater metro NY? I would DIY but only if there are some really idiot proof instructions someplace. TIA as always.
