Over the years our trucks get wired/rewired different ways. Hopefully you have a wiring diagram; there are plenty of sources on this site. That being said, power runs to your ignition switch. When you turn your switch to the "start" position, power goes directly to the distributor - 12 volts. When you release your switch and it goes to the "run" position, 12 volts goes to your ballast resistor, and from the resistor to your distributor.

I've seen wires running off the resistor to power the wipers, and a number of other ways. Just learning how it is supposed to be wired, then see what you have, then you will know what needs to be changed-if anything.
