There is a Module of some sort behind the battery mounted inside the fender well has about 10 wires going to it..I see No other source anywhere for ignition so maybe that's it..When my wife gets home with the smart phone i will upload a better pic of the module

Here is another of the plug that is supposed to be plugged into the distributor i suppose...Looks like i have a mess to figure out..But for what it's worth it run's very good but i want my vacuum advance fixed..

That would be it. Same location on my 86. I have had the same plug hanging from my truck's wiring loom near the dizzy since I have owned it. From what I found in the FSM, that is a dizzy plug for the vehicles built for California emission. I'm in Minnesota, hence, there was no need for the plug

So what i need to do is change out the Dizzy with a vacuum advance and finish the hei conversion..Then i will be set

And probably swap to an older carburetor with the correct ported vacuum advance for the distributor and make sure that the electric assist for the choke thermostat still works properly.
