My two cents worth. I originally went with the 100 dollar harness from Chevy Duty for my 52. It was easy to install and worked fine. After a couple of years i decided i wanted a more authentic look and bought the premium harness from Jim Carter which is made by Vintage Wiring of Maine. I think the quality is good and it looks nice but but had some problems with the install. A couple of the wires were mislabled and the instructions refered to illustrations which were left out of the kit. Also, turn signal wiring is not included with that harness.
