A 6-way trailer wiring connector would normally carry the brake output circuit as long as a brake controller is installed in the vehicle. That said, we do have a 6-way to 7-way adapter part # 337TC1067P which is a simple plug in adapter that will convert your 6-way to a 7-way.

If you wanted to just replace the 6-way with a 7-way you'd want the part # PK11898 which comes with wiring, the socket, and a mounting bracket.

If you don't have a brake controller installed the best option is the Prodigy P3 part # 90195 which is our best selling brake controller because of how well it works and easy it is to use.

Next, for a wiring kit to install the brake controller to the 7-way (or 6-way) you would want the Wiring Kit for 2 and 4 Brake Electric Brake Controllers # 5506. This will provide the power source and ground for the wiring for the brake controller. You will need to test the wires from the brake pedal switch of your vehicle to find a circuit that has voltage when the brakes are applied and none when not applied. This will be the circuit you will run the red wire to.

Finally you will need to run a length of 10 gauge wire (part # 10-1-1) from the brake output circuit of the controller to the brake output circuit of the 7-way (blue wire). The # 10-1-1 is sold by the foot so you will need to order a quantity of the amount of feet you will need.
