This is not an easy installation without a wiring diagram of the brake switch. Maybe some one can post one. There are some problems with the park-neutral switch that could shut down the starting system if you get it wrong as well as a risk of PCM damage- I'd be darn sure of what I was doing before I went ahead.

ah come on... That thing have only 4 wire. (Brake Controler)
Wire 1 : +12V (Battery) + 20 Amp Fuse...
Wire 2 : Ground
Wire 3 : Output (to the Traileur Brake)
Wire 4 : To the Brake Switch.
Wire 4 is a Input for a 12V signal
BS
+12 -------_------ Wire 4
(BS - Brake Switch)
That switch have 6 wires, I will have to poke around with a multimeter to find which wire I have to splice.
