Wiring harness 63 C10
 

Anyone have any info on where I can get firewall electrical connectors, kinda fried mine because I forgot to cap a wire when I removed the radio. It goes to the front lighting, horn, alternator, etc. and is on the left side of the firewall. I would like to replace both pieces.

Looking for that wire harness too.

American Auto Wire has everything your asking about….

I know the Truck Shop has the grommets.
M&H Electric has the harnesses (original type).

It’s not that difficult to unwrap the harness, replace wire, clean terminals and re-wrap the harness if you are so inclined. AAW has the 9 pin main plug and the 6 pin engine firewall connector plug and packard terminals if needed.

Thanks for all the replies!
Turns out, it wasn’t that bad. That connector and wires were all ok.

Great that you fixed it, but for reference, I just got that harness from Classic Parts. Item #52-230 and it's not too bad for only $39.95
