Brake Controller Installation: Starting from Scratch

Question:

i have a 7blade socket with 4 wire flat plugin.where do i connect the loose black and blue wires, i know the white is the ground wire.

asked by: hopkins

Expert Reply:

The black wire coming out of the 7-way connector should be connected to 12 volt power from the vehicle battery. The blue wire connects to the trailer brake feed circuit coming from the brake controller mounted in the vehicle.

If you need to run these wires for your connector you will need a 40 amp circuit breaker, item # PK54540, to attach the black power wire to the positive battery terminal. You can use the Wiring Kit for Electric Brake Controllers, item # 5506 and the 40 amp circuit breaker mentioned to complete the installation.

I have provided a link to brake controller installation instructions that may help.

What our customers are saying:

I just wanted to let you know what a pleasure it wasdoing business with you. I ordered on Sunday night, and received my hitch today(Wednesday), and installed the hitch and the wiring harness tonight in about 1.5 hours total. The hitch lined up perfectly and bolted right to the frame. My infinity was a little hard to get to the wiring, but once I got to it your plug worked perfectly. I have already recommeded you to a friend and will continue to do so to others. Also, wanted to let you know how amazed I was that you had a custom hitch for an Infinity QX-4, most places I checked only had hitches for Ford, Gm, Or Dodge products. Thanks again. It was a pleasure doing business with you. Dudley
