Truck Won't Run

[RustyPile]

I thought I gave a pretty good description of those wires.. OK, I'll try again.. The resistor wire runs from the coil through the harness to the firewall plug. It is readily identifiable as the insulation is cloth like instead of the normal vinyl. Also, it will probably have a faded appearance.. And as you stated, the yellow wire runs from the coil down to the starter.. The 2 wires are joined together at the coil terminal..

Remove both wires, they're not needed, especially the yellow wire as it is "HOT" when the ignition is ON... Separate the firewall connector by removing the bolt in the center. Using needle nose pliers, reach in and grasp the terminal on the edges and squeeze it.. This releases the "catch" and the terminal can be removed. Here is a link to the replacement terminal.. No need to order online, most parts stores have them in stock.

[EDIT] Here is a link to the proper terminal and plug for connecting the new ignition wire to an HEI...
