Question:

I replace my bumper with an aftermarket bumper. I need about a 5 inches more to plug it up. It has a factory 7 flat wiring harness. do you have something that might work.

I do have a solution to extend your 7 way to reach your new bumper, the Tow Ready Replacement 7 way Harness and Socket part # 20147. It provides you with an additional 17" of wire, and a US car connector to plug into the back of the seven way connector. You will cut the existing connector off your truck, and crimp the new harness on with the included butt connectors, then plug the connector into the back of the plug.

If you need a new socket also, I recommend the 7-Pole and 4-Pole Trailer Connector Sockets w/ Mounting Bracket and Wiring, pat # M40975-11998. It gives you a 7 and 4 pole connector in one plug, and gives you an additional 4 feet of harness.

I attached a video of the harness being installed for reference.
