Truck is a 67 with a 5.3 LS Swap. As you can see from the picture, my Red 12v feed wire and Pink IGN COIL wire are melting at the ignition plug. I know the pink wire feeds through the firewall bulkhead and originally fed the Ignition coil. I believe it also split off and feeds something on the underdash fuse panel. When I swapped to the LS, I did away with the stock wire coming out of the firewall bulkhead on the engine side and ran a new wire to feed with Engine Harness with 12v to the PCM etc. I also have Relays for Fuel Pump and Electric Fans. What would be causing these wires to melt?
