Racer 71 is right. A new F-150 will have the truck side controller harness hidden just under the dash below and to the right of your right knee. The 12" pigtail assembly that plugs into it came with the truck and was probably in the glove compartment when new. All you have to do is splice the controller wires onto the provided harness.
I left my controller with a 3' set of lead wires. I made a little stand for it and it sits on the dash when towing. Otherwise, I unplug the controller and harness and store it in the back seat. That keeps that dash area clean looking the rest of the time. Most controller installations I have seen look like an aftermarket cassette deck done by a 19 year old back in 1974. Don't ask why I would remember this vision.
