Good Evening,

I have a 66 that has several alterations made to the wiring harness by past owners. I have spent quite bit of time running the wires to no avail in some cases, I have decided to R&R the harness. I have been considering the following products:

- Painless https://www.painlessperformance.com/...pala&sb1=Go%21

- Autowire. https://www.jegs.com/i/American+Auto...SABEgJHw_D_BwE

Any reviews or recommendations?

Additionally is there a schema or checklist available on where to start and what the best approach is to undertake this exchange.

Any help is appreciated Thanks

John

I used American Autowire on my 64. I have been pleased with it. Support is good if you have questions.

I rewired my chevelle with AAW kit, great tech support and customer service. for best price buy from Matt's classic bowties

Additional for American Auto Wire. I've dealt with them direct and through vendors. They know their stuff.

I've replaced everything in my car with their harnesses except the intermediate harness.

I should add, I was surprised how easy it was to install all new wiring. I thought it would be a huge job, but everything just kinda fits in place.

Do you know if AAW is selling just the fusebox on its own? I plan on doing some custom things and the whole wiring kit would be a bit wasteful I think.

You can find fuse blocks at summit racing or ebay. Figure out how many circuits and go from there. When I was wiring my Cutlass I added a 6 gang box for El. fans, fuel pump, radio, LED headlights and fans controller. I also added relays for each of those components.
