Electric trailer brake controller recommendations needed

[Trophy Truck]

I installed an electric brake controller to my existing harness (4 pin connector next to the parking brake wire cluster) under the dash and smoked my brake controller. I double checked the wiring and the new brake controller and it caused my brake pedal circuit not to function... example - could not move shift lever from park. Bob, suggested that I look at the fuses and circuit, I removed the brake pedal wire harness and was able to move the shifter... which reminded me that this was a brake circuit issue so now I removed the darn brake controller harness. The truck harness from left to right reads

1 terminal (brn/red strip) = 12. 51 vdc

2 terminal (green)= brake pedal voltage starts out 0, half pedal reads . 5 vdc and full pedal reads 0 voltage

3 terminal (white/brown stripe) = brake pedal voltage starts out 0, full pedal reads 12. 51 vdc

4 terminal (black)= ground



With all that said, I stopped trouble shooting for the moment and looking for possible reasons... why the original brake controller smoked. I will look at the harness on Wed. Thanks

Either someone before you miswired the harness or you miswired your brake controller to the harness.

I don't remember what color wires are in the factory brake controller harness but a standard electric brake controller should have four wires.

1. Black is 12vdc.
2. White is ground.
3. Red is stop light signal in which is used to activate the brake controller when brake pedal is depressed.
4. Blue is braking signal out to trailer brakes.
