anyone know what and where these 4 wires are for ?
I was looking under the hood and found these 4 wires up by the brake master cylinder. Looks like they are part of the trucks stock wiring but no pig tail or anything that looks like they go to. I also found a exhaust probe wire that is just laying under the hood.

 

they are the wires that go through the fire wall for the up-fitter switches...if you wanted to connect anything in the engine compartment to the up fitter switches, use these wires,ford ran them through the firewall for us..the other end is under the steering wheel and would still have to be connected too.right now they are not connected to anything,one end is there and the other end is near the upfitter switch fuse box

 

They don't HAVE to go to the upfitters, but it sure is nice! I ran some foglights off of them and it was one of the easiest wiring jobs I've ever done!

 

I ahve those same wires in my 07 F350. But they are hooked up to the wires that Ford installs for an after market alarm system/ . I ahd a Tech at Walnut Creek Ford tell me what they were for. He just said it was for an alarm. I had thought it was all for a satelite phone system.
