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?
