To install a 7-Way trailer connector on a 2018 Ford F-150 with a factory 4-Way, you will need to use # 37185. This is part plug and play and part hardwire, but the hardwire locations are easy to access. You will need to ground the white wire to the vehicle frame. The purple wire is for reverse lights if needed.

The blue wire is for the trailer brakes and the black wire is for 12 volt power. To connect these wires, follow the factory 4-Way wiring back until you find the connector on the driver side frame rail. This connector has more wires going into it then coming out to the rear of the truck. Pull back the covering on the forward side connector to reveal the wires. There will be an orange wire for 12 volt power and a blue wire for the trailer brakes. Tap into those to complete installation.

I have included a link to an FAQ and a picture that will help with installation.

For a brake controller I would recommend the Prodigy P3 Brake Controller part # 90195. This is one our best selling brake controller because of how well it works and how easy it is to setup. This is a proportional brake controller that senses the amount of braking the tow vehicle is applying and applies a proportionate amount to the trailer brakes. This will be the last brake controller you buy as it is incredibly reliable, works, well and is easy to use. It can easily be transferred to future vehicles as well.
