Coil Diagram
I have my donor engine in my 79 F150, 400,C6,4x4. Have everything but a spark. Now this truck had some creative wireing when I got it. U ran an HEI distributer in the engine I want to re-build. The HEI distributer's shaft is too short and I can't use it.
I have a new ignition coil, but with the butchered wireing, I'm stuck on what should go where. I need help.

Cool, sounds like you're close. The distributor connects to the module completely; looks like you've got that straightened out. The ignition coil connects at two places - the negative side of the coil goes to the green wire coming out of the module, and the positive side of the coil is connected to hot-in-run through a ballast resistor while then key is in RUN and straight to full voltage when the key is in START. The red wire on the module goes to hot-in-run, and the white wire on the module goes to hot-in-start (it's a spark-retard signal). Here is a diagram:

Idle
Well the engine I knew nothing about, seams to be strong as an ox. Sounds really good, oil pressure goes to just to under 55 pounds warm. Almost sounds like it may have abit of a cam in it. Sounds like it has a vacume leak, but it seams to be just from the opening of the carb. But I can't ge it to idle. But it is running. And I'm petered out.
