If your looking for this because the alternator keeps going bad, it is a wire running from the alternator to the starter, it runs against the firewall on the passenger side there is a fuse 175amp more than likely blown as was mine and i didnt find it till after the 4th one. took some research but i did find that little sucker, easy to replace with a 9/16 socket and i bought a 175amp fuse and block from a stereo shop works fine havent had a problem for a year now. The problem is the way Ford routed the wire it gets hot and the fuse melts on the inside. good luck.
