Installing a 4- to 7-Way Adapter and Brake Controller on a 2005 Pontiac Vibe

Question:

Ive installed before pin trailer connector from the trailer sometime back. I recently ordered a seven pin connection kit which I also receive from you. My trailer has a prodigy braking system how do I connect the blue wire for the braking system to where do I hook it up. Also how do I hook up current to provide power for my camper battery.

It looks like you have ordered 4- to 7-Way adapter # 37185 and a 40 amp circuit breaker, # PK54540. In addition to these parts I also recommend wiring kit # 5506. Use the wire that comes with this kit to attach to the blue and black wires on the back of the 37185. Run them under the vehicle towards the front avoiding areas that can pinch or burn the wire such as exhaust and suspension parts.

The wire that is for the 12 volt circuit on 37185 (black wire) will connect to the vehicle positive battery terminal via the 40 amp circuit breaker. The other wire, which connected to the blue wire on 37185, will have to be routed through the firewall and to the blue wire on the brake controller.

With any left over wire, attach one end to the brake controller black wire, run it through the firewall, and attach it to the positive battery terminal via the 30 amp breaker included with the 5506 kit. The white brake control wire will need to run to the negative battery terminal.

The red wire goes to the cold side of the brake switch located above the brake pedal. Test the brake switch wires with a circuit tester such as # ALL640595. Find the one that only has power when the brake pedal is pressed. If it has power with the head lights or turn signals on it is not the correct wire.

I have included some links that will help with this installation for you.
