After looking, it looks to be a huge deal to just do even the motor parts. Maybe not, I will have to look harder. Either way, is there somehow I can test my coil to see if it needs a resistor or not. The box has been tossed, and I want to say it was the "OE Style" one that I bought but I want to make sure before I go and blow something up haha.

A resistor won't hurt and if OE style not Racer Style then a standard ballast would be fine.

This is one of the options I was looking at for wiring. You can buy just the box and or their wiring. http://www.enoscustom.com/blackbox.html

If it is the OE style, I still need a ballast correct? I really don't want something to short of catch fire or something haha. I really don't like electrical stuff that I don't know about. figured a harness may let me figure it all out if i wired it fully myself. may be too much of an undertaking though.

You need the resistor wire or a .6 ohm to .75 ohm ballast resistor. A ballast resistor is not just a ceramic high wattage resistor. It changes value slightly with higher temperature caused by higher RPM. This lowers the resistance a little bit to allow the coil to build a hotter spark at RPM.

Without the ballast resistor only the coil will get hot and melt the windings inside the can and cause a short.

Aftermarket ignition systems can do away with the ballast resistor. The way to tell. If the trucik harness hooks to the + side of the coil you need a resistor. If the Ignition Module takes place of the truck's + wire then you don't need a resistor unless the coil says to add one.

Well, I am using the stock dizzy, but with the accell 2020 pt. elim. kit. Sorry for all the questions, just don't want any mishaps.

The Accel kit uses the ballasts wire from the Factory as long as the coil is stock or near Stock (OE)

So, long as my coil is OE, I should be fine, and not need anything extra, is what your saying? Ballast wire is the pink wire, correct?

Yes to both questions.

Points coils are 6volt. need resistor. The solenoid jacks it to 12volt
to help starting. It will run a while at 12volt, but somethings gotta give.

You are asking if you can test your resister wire?? Yes remove wire from coil ignition in run position, volt meter on 12v volt scale, you should 7 to 9 volts on wire.

maybe we got off track here....

I bought a coil from autozone, supposedly the "OE" style coil. Is there a way to figure if it is a 6 volt, or 12 volt coil? Someone said the stock was a 6 volt? If it is the 6 volt one, im fine, if its 12 volt, i need a resistor...

for our trucks 67-72 is 12 volt if you bought it for your make model it should be 12volts, you should be able look it up at Autozones web site by part number, if you still have box receipt.
