I had RIW duplicate the main harness as I had a NOS Miller wiring harness. As far as I know, Miller did not sell the dipswitch wiring with the harness. It was a separate item to be purchased. Thus, we had to guess about the dip switch harness, but it was consistent with the main harness.
The main harness replica is quite good with all the details done correctly to the original, except, RIW could not duplicate the odd-shaped ground tab. The wire lengths were copied from the original. They have a good inventory of vintage wiring supplies, but special items that have odd shapes were not produced by them. There were no PR38s in the harness kit.
