I just completed an overhaul of my trailer and may have messed up the brake wires. I have attached a picture showing the wires connected which should activate the brakes through the controller in the truck as well as the connection to the break away switch.
The three wires on the left are DK blue from the 7pin cable, the Med blue is from the trailer brakes and the LT blue is from the break away box. These have the red marrette.
The three wires on the right are BLK from the 7 pin cable, the ORN/BLK is from the break away box and the BLK/WHI is a jumper cable from the breaker fuse on the front of the trailer.
I checked to see if the break away box was working by pulling the pin out and checked it with a tester which showed it had power. The box got quiet warm to the touch and the brakes did not activate like they should have.
Is there something wrong with my wiring? OR, is there a problem with the wiring at the brakes? OR, hope someone can tell me.
