Brake Controller and 7-Way Recommendation for 2016 Ford F-150 with Factory 4-Way
Published 06/06/2019
Question:
I have a 2016 F150 XLT. It does not have the factory Max tow package. I installed the hitch myself. It does have the factory installed “flat style” trailer light connector. I also have the OEM brake controller adapter harness. I need to convert it to an Rv 7 blade connector, and I would like to install my trailer brake controller. Do you have a plug and play harness for both of these issues?

For your 2016 Ford F-150 the brake controller I recommend is the Prodigy P3 part # 90195 which is the most advanced and easiest to use brake controller on the market that senses how hard you are applying the truck brakes and applies the same intensity to the trailer brakes. To convert the 4-way to a 7-way and install the brake controller would actually want the part # 37185 and the brake controller install harness part # 22292. There are a few connections that need to be made at the rear of the truck as well.
Follow the 4-way trailer connector wires from the trailer connector to the front of the vehicle. These wires connect to a factory plug along the frame rail, usually on the driver's side, between the back tires and the rear bumper. The factory plug should be mated to another connector which has wiring that continues back toward the bumper.
There are more wires coming from the front of the vehicle than there are coming out toward the 4-Way plug. Ford wires the front of the vehicle as if it will be manufactured with a 7-Way plug, so all the 7-Way wires are run to this connector on the frame rail. This allows a 7-Way wiring harness to simply plug in line with the wiring coming from the front of the vehicle. If the vehicle were made with a 4-Way plug, it would plug into the same connector. Because a 4-Way plug would not require them, the additional wires are terminated at the pictured set of mated connectors.
