It comes from the fuse box ,then goes behind the engine in a harness...actually it begins at the ignition switch,then goes to the neutral safety switch,then to the fuse box,comes out of the firewall side of the fuse box,then behind the engine to the starter..it is put in a metal conduit pipe thats bolted to the bellhousing factory,and I've seen the wires in that conduit get roasted many times !--the two red wires going to the large stud on the solenoid are in that pipe too..
