hey guys, been a while since i posted for help but i have a good one for you. im having a tough time finding information on the brake wire for an f-650. the truck is strange because it is an f-650 front and frame but just the cab is from an f-450 but the brake system is all f-650, therefore the info for an f-450 doesnt match up. it would be awesome if someone could post a directechs sheet on this truck. the truck is a 2008 i believe but could be an 09. thanks

Parking brake or foot brake? If parking brake there will be only one wire on that switch, that is the wire. Foot brake will have 2 wires going to it. One will be constant 12v, the other will only get 12v when you depress the brake. The latter is the one you need to tag.

looking for the foot brake wire. i have tested the wires at the brake pedal. there are two plugs at the brake pedal with two wires on each plug and none of those wires test as a brake wire.i tried testing with the key on as well and still nothing. the brake pedal looks like its just an air valve that connects to a larger system and none of the info i have is any help either

Back of vehicle, test at bulb then follow forward to kick panel.

Amateurs assume, don't test and have problems; pros test first. I am not a free install service.
Read the installation manual, do a search here or online for your vehicle wiring before posting.

the parking brake is also an air release valve. this truck is more like an 18 wheeler than a normal truck
