I'm trying to help out my dad with his 2001 Screw F150 and brake controller wiring. I have a 2003 Screw, so I can look at mine to compare.
His came with the tow package, but I suspect they didn't include the relay/fuse/pigtail with it. He bought the truck used and it has 100k miles on it. So I'm sure that kit is long gone.
He bought the pigtail and wired in the controller to the connector under the dash, but the controller doesn't have the hot feed going to it. I suspect it's missing the fuse and relays that are supposed to go under the hood. Can anyone tell me what fuse position is needed and what relays are needed?
Thanks. I dug out my PDF of the owner's manual and took it to my truck. On my truck, I have all of those except the full relay and the reverse half relay. So I'll be calling my dad tonight to see what he has. I'm also thinking he may have a blown that 108 fuse. That might explain why he has no power to the brake controller.
BTW, my manual and truck show:
302: Trailer tow battery charge relay (Full relay)
201: Trailer tow park lamp relay (Half Relay)
203: Trailer tow backup lamp relay (Half Relay)
After talking to my dad, I found out something else odd. My truck came with the factory tow package. His didn't. He was able to find the wires under the truck at the rear to mount everything up for a 7 pin plug. Even the tap for the electric controller is there. But when you look at the fuses, Fuse 101 was not only empty, there was no blade for the maxi fuse to connect to. One blade was there, the other wasn't.
I figured out how to pop my fuse box up and turn it over. I was able to see the bottom side of fuse 101 and see that there is a dark green solid wire to mine. I let my dad know. I'm hoping that wire is there in with all the other wires and he just needs to plug it in at the bottom.
