viven44 Posted March 5 Share Posted March 5 I think it comes with a ceramic ballast resistor, like a Mopar. Yep that correct, but the Ballast is not needed if the coil you are using doesn't need one. The truck I had actually came with a GM HEI distributor/coil setup that didn't need ballast. The wiring was a bit easier and the ignition modules were more readily available, cheaper. If its not Ford Wiring anyway, then why not try something else. It was a Franken-Truck. Check out pg. 43 here for more info on Coil wiring. https://www.painlessperformance.com/Manuals/10102.pdf This even has wiring diagrams for 1G/2G/3G alternators.

Those GM modules in an HEI suck up enough power that the coil is never going to saturate. Get one for a Tornado and you can set it up to have ignition retard while cranking..... 💡 Link to comment Share on other sites More sharing options...

Get one for a Tornado and you can set it up to have ignition retard while cranking..... 💡 I've seen that a lot over the years and it does work great. I think I'm going to take the ignition module and coil harness out of the '82 F250 along with a new square coil that you suggested and see what happens. I did finally find the original engine side distributor plug in that mess. The former owner didn't have it running through an ignition module in this '86 302. Matter of fact, there was no ignition module in the truck when I got it Jim. Lol Link to comment Share on other sites More sharing options...

If you're going to run a DS-II module you should probably use the horseshoe connector and the cylindrical coil.

You did tell me that coil can be full power. I take it the '82 trucks were DS II cylinder coils? Link to comment Share on other sites More sharing options...

Some time during the 85 MY 302's became 5.0l EFI. Then they got the square coil. 300's were next. The 460 & 351HO continued DS-II & carbs into 1987.
