65 C-10 Underhood wiring- bulkhead plugs - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have 2 plugs coming from the firewall, one is located near the LH inner fender and the other is just just above the RH valve cover. I'm thinking that the LH one feeds the front lighting and the one above the valve cover is the gauge feed, coil power and crank signal to the starter. Correct?

Should there be a wire to a junction block to supply power to the ignition and dash (like on the 67-72 trucks)? Someone had added a large gauge wire from the fuse block through an extra hole in the firewall. I'm not sure if this is what was being used or not?

Any source for a decent wiring diagram?

Thanks,
Jason
