First of all, I've completely rewired vehicles before without any trouble, but my '66 C10 is causing me to scratch my head a little. I doubt it would be hard at all, if I had something to start with. Under the dash back to the tail lights appears to be original, unmolested, and in good shape. Not so much for under the hood. When I got the truck, it came with no motor, and it seems like all the wiring under the hood was hacked to pieces when they pulled the motor, as I seem to be missing quite a bit. Ordinarily I'd just buy a complete new factory harness, but I really just need what goes under the hood. I'm missing all the battery cables, solenoid, and ignition wiring from what I can tell. As you can see in the pic, I have some wires coming out of the firewall to the right of the heater box, and no clue what they are for. I have the plugs for the firewall bulkhead connector, but most of the wires are cut. The headlight harness seems to be intact. I plan on installing a MSD ignition box, so I'll just need to know which wires go to the ignition switch. Ideally, I'd like to just replace everything up front, either with new, or an uncut original.
