Expert Reply:
To install a brake controller in your 2008 Ford F-150 you would be able to use the brake controller port under the dash and you will need to complete the wiring at the rear of your vehicle to the 7-way at the rear of the truck.
For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is 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.
The install harness you would want is the part # 3035-P and then also the part # 37185 to convert the 4-way to a 7-way. I attached a help article that details how to complete the wiring from the frame rail to the 7-way as well.

Well hi there I’m Colby, i’m really needing help with my 2008 Ford F150 STX. I’m just installed a primus IQ P#90160 brake control system no problems with the wiring kit P#3035-P. But cannot find any wiring diagrams for the back of the vehicle trying to install a seven way P#47185 cannot figure out where the brake control wire or the Auxiliary power lead goes everything else seems pretty simple other than the reverse wires confused as well. This is for a travel trailer by the way. Please help, thanks
