engine stand wiring harness
Depends on how complicated you want to get. You have a fuel pump. or electric gauges to hook up?
Or just igntition/ starter?
What ignition system you have, stock Mopar ECU? Do you know if it's late enough that it has 2 terminal ballast resistor, or older 4 terminal resistor, Or is it some aftermarket igntion?
You happen to have a spare Mopar ignition switch laying around?
