Been thumbing through service manual all night and can't come up with the answer. HEI remote coil. 1 plug with 2 wires from ign module. Believe they are c&+. Second plug to the coil has +ignition on and tach out. External HEI coil is fried. Tests infinate open. Have one of those handy 50K volt coils in the box, been sittin there collecting dust for a couple years. Can I run the two wire coil somehow?

If the external coil you have has the two connectors that are sort of "D" shaped -- the two are both parallel wired! No idea why GM opted to do it that way... but what is, is what is! :)
One usually has a pink & white wire, the other varies it seems.
But the pink will be a switched power, the white goes to the module (used to go to a set of points!! heh).
Take a look at this:

It's for a V6 Fiero, but that doesn't matter - look at the upper drawing, it shows the coil. Does that make more sense now? (picture saves 1K words!)
