    I need a ignition wire for my plow setup and was wondering who used what.
    I was thinking of using an upfitter switch, but can't find their wires either.
    Any Help?:confused:

    I hooked mine up to the radio fuse in the fuse box for my Western power wire.

    upfitter switch wires

    On my 08' f-350 6.4 the wires for the upfitter switches were a group of four wires taped together up under the dash on the driver side, behind the emergency brake. They had shrink tubing on the ends and the color pattern is in the owners manual. There are other wires under the same area with shrink tubing on so make sure the colors match.
     
  5. the other posts cover possible power sources(i used a spare fuse in the in cab fuse panel that comes hot with the key, if you can fit a spade terminal on the acc side of the fuse you have a fused source as well) other note of interest is that ford has four pass through wires already in the firewall. Engine bay side is near drivers side inner fender wall blunt cut, the other ends are near the upfitter switch feed described above

    Thanks for the help guys! I guess I will be digging into the underhood fuse box since it is the easiest to get to or the upfitter switch.:waving:

    Drottlawn -

    Under the dash, behind the diagnostic link connector, close to the wires for the upfitter switches and PTO loom, there is a small purple wire that will be hot in the run position of the ignition switch. It's a blunt cut wire that will handle up to 10 amps.

    Just my .02¢

    Sorry, but I haven't been on here much and I didn't know you replied to the thread.

    I'm sure you found it by now, but it's a 10 amp fuse located in the number 44 slot of the smart junction box.
