Pertronix II units do not require a ballast resistor. The module wants full 12 volts. There is stuff all over the internet on this topic. Just type into Google: "Does Pertronix II need a ballast resistor?" and you will see. So, just remove the hack-wired resistor and run a wire directly from switched 12v (IGN) on the ignition switch to your unit per wiring instructions. You can also branch off this wire through an inline fuse to feed your radio and electric choke.
For Electric Auto choke hook up.
If your truck is a 70-72 it has a pigtail just inside the engine bay fire wall, it's about 4-6" long coming out of the wire loom by the rear valve cover. This is for the auto choke feed hot wire. It's end is female long black rubber socket about 1/2"x2" long
Not any other wires should be hooked into the pink dizzy hot wire like john says..

Thanks for the input, but I already knew the resistor had to go.
