I'm guessing there is wiring as well? because the controller is just the box, no wiring, no looms and if the switch assembly arrives same then we are still missing bits.
It's - 22C here so I'm not shlepping out to a breakers to disassemble an f-150 to check
According to the F-150 forum the wiring harness is already inside the dash, once you remove the two screws and the cubby, you should see it.
