In the wiring harness, the trailer brake wire should be the heavy Dark Green wire. If not familiar with wire gauges, the smaller the number, the heavier the wire. 14ga is heavier that 18ga.

Wire colors/sizes from wiring diagram -

Ground - Black 14ga
+12V - Red/violet 12ga
Elec Brake - Dark Green 14ga
B/U - White/Red 18ga
Park - Brown 14ga
Left turn - White/Orange 18ga
Right turn - White/Dk Green 18ga

Based on you symptoms, I think there is an issue at the trailer connector in the bumper. Look carefully to see if there are any terminals touching. If available, plug in a trailer connector with no wires, and see if the problem still exists.
