2004 dodge ram, with bully TC 301 brake
controller. I have the controller, yellow wire, which is the output to the trailer brake connected to the light blue truck wire to the trailer brake at the back of the truck. I have the red wire which is the 12v power connected to the truck red/white which is live 12V constant. I have the black wire which is the ground, connected to the black truck wire, also ground. That leaves the blue wire which is supposed to connect to the stoplight switch. I connected that wire to the truck white and tan or orange, 2nd pin on the switch which is supposed to be the brake switch sensor. When I hit the brake. the 3rd brake light fuse blows immediately, and the trailer brakes do not actuate. The squeeze button on the controller, does operate the brakes on the trailer. The truck brake pedal does operate all the lights on both vehicles normally with the exception of the 3rd brake light. That blue controller wire, is supposed to supply 12v power to light all the lights when the hand brake is applied. When the foot pedal is applied, 12v's should flow out of that w/o wire, to actuate the controller and apply the trailer brakes. The controller does what it's supposed to do, but it doesn't get to the trailer brake wire, it just blows the aforementioned fuse. Which brake switch wire am I supposed to connect it to?? The wires are as follows on the brake pedal switch. White/red, white/orange, purple/white 12v live all the time, purple/yellow has 12v live until pedal is actuated-S/C brake, black/orange, green/white. If i unplug the connector on the brake controller, and replace the 3rd brake light fuse, every thing on the truck works normally. Please read this carefully, I don't believe I left any thing out. Except, Help.
