wiring burn out from fuel shut off
 

I was driving home last night when the inside clip on the fuel shut switch came off right as I opened the hood to see what was wrong it sparked (ground out) half a second later on driver fender wire went up in smoke it was a fusible link wire and Im not sure how stock the wireing is as last owner did auto to getrag swap I did see a stickey on these trks for replacing fusible link wire to maxi fuse but I don't have the time for that yet any wiring diagram for that part of the trk would really help!!!!! this is my 2nd first gen didn't get time to know the first one it was totaled 8 weeks after bought her so pretty much a Cummins Virgin so any help will be very appreciated
