Evaluating old Wiring Harness

@Miranthis I had a similar situation with my Dart when I first bought it. The previous owner had shoved a screw into the bulkhead connector on the main power feed. My buddy saw it, laughed and took it out. When I went to start it, nothing. So we rode with the screw for a while. That hole in the top of your's reminds me of that.

Year One carries this one and also a version if you're running a Mopar electronic ignition box. It is a good quality piece and everything is well marked. Pricey? Yes, but so is being stranded out of town late at night.

When I swapped engines, I went with a new under hood harness and never looked back. It wasn't cheap but it's good insurance. If you need any help, I'm over in Lee's Summit, but work in Merriam. Give me a shout.
