1980 Chevy C10 - Ugly but Functional - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Wow! And I thought going from a 250-six and manual trans to a 350/TH350 was a lot of work. Great job!

Just FYI, when you get around to replacing the wiring with a generic harness, I highly recommend an American Autowire kit. I used their "Power Plus 20" kit. https://www.americanautowire.com/shop/power-plus-20-kit

Got it on sale and had a discount at Summit Racing, so paid around $260 for it. The materials (including GXL-rated wire), diagrams, and e-mail & phone support were first rate. The kit even includes their #510476 charging circuit kit with 6 gauge wire, terminals, and two maxi-fuses and holders.

I did need to buy a instrument cluster connector, because I didn't want to re-use the old one. Also had to reuse/modify washer/wiper wiring and connectors. There's also a few other gotchas, but the kit has circuits to spare!

The fuse panel will bolt directly into the factory holes on the firewall, but I made a plate to cover the OE hole. I also used standoffs on the inside for more room between panel wires and firewall. The distribution stud in the picture is something I added to feed the ignition switch and IGN fuse panel bus independently. The stud is fed by an 8 gauge wire, instead of the 10 gauge wire in the kit.
