If it was a race/stock car and they ran a wire from the starter batt stud in to a momentary contact switch and out to the starter small solenoid stud it'd work but I dont think that's the case here. I had harness probs and I finally just bought a good used complete underdash harness from a good guy (Steve Remington) on FABO. I finally realized the time to sort it was a waste and you're in a worse spot with burnt/hacked stuff. Good luck w it. PS What is LMAO ? Only acronym I never used on here EDIT & that in/out would not be thru the bulkhead but 2 seperate firewall holes/wires
