My step father in law (guess I have to call him that now huh? lol) said they put in a donor harness after the fire. I do not see any signs of a fire so I'm inclined to believe they did BUT there are so many wires just dangling around that have been cut it's nuts. This is some of the worst spots. Fuse box looks horrible o.0
Upper left, cut wires.
Bunch of cut wires...
I do like the idea of yours to just grab a donor engine harness. Think it would be easier then tracing all the stuff in there.. I'm not even sure if it is a harness for the same make/model o.0 They really did some "funny" fix's on this truck and it may end up being a nightmare to correct but man I enjoyed hearing it running again yesterday. Actually took her around the block slowly and set off a bunch of car alarms. Guess the cherry bombs are completely rusted out like I thought they were... why they put cherry bomb glasspacks on... I don't know.
