American Autowire has been very helpful. One of their staff Aaron has helped me identify the fuse box in my car and it is a Chevelle fuse box. The dash wiring harness is still unknown as I know the ignition switch in my car was GTO style not Chevelle, therefore, the Chevelle and Beaumont are not interchangeable.
We would need an engineering diagram, OEM part number or two harnesses side by side to be sure of what we have, and if their is any interchangeability.
Does anyone have a part number for a 1966 Beaumont 2 Door Sedan, automatic trans, with dash warning lights, under dash wiring harness? If I had this number, American Autowire can see if it is interchangeable with any US made car wiring harness.
Also, does anyone have a suggestion where I can buy a manual for this car? I have a 1967 Chevelle manual, but I would like the right one for this car.
Its been a long time coming but here is what I have found out:
I found the OEM part numbers for the 1966 Beaumont dash harness:
3394195 for bench seat or 3394197 for buckets or sport, of course not available and no compatible US car used those numbers.
Aaron Brownfield at American Autowire helped out enormously and got me the pieces I needed to build and repair what I had. I highly recommend them!
I do have a question for the experts out there: On the front right near the battery, behind the headlamps is a wiring connector in my new harness that must hook to something that has been removed from my car over the years. The wire is red, about 10 Gauge and has a small eyelet on the end. I believe it must be one of the main power wires and goes through the harness to the bulkhead connector on the left side firewall. My harness was so hacked over the years, so stuff is missing and bypassed and I have to start fresh. Any help identifying what I am missing would be appreciated.
sounds to me like you're missing the junction block. It joins the red wire you're talking about, and the fusible link (if used) to the positive battery terminal. On my 70 2+2, it screws to the radiator support behind the battery. I have spares if you want one.
I am interested in the Beaumont wire harness you have and the pontiac emblem and tack for console. I have a 67 Beaumont 327 automatic. (rrbedard@verizon.net) BOSSY
