GM HEI conversion questions
It's just like the diagram I posted. Just mount the HEI in the bottom of the box. This is a box I "had" so I no longer know where I got it, but Radio Shack used to / still may, and places like Digikey, Mouser Electronics. Not critical.
There's an "tit" on the bottom of the module you must either break off, or drill a clearance hole so it fits flat. Mount with simple machine screws and nuts, and use the heat sink thermal grease supplied with the HEI
Then just wire the distributor plug to the two indicated terminals. Don't switch the wires. You can get a plug by buying a 2 terminal "trailer connector" at any parts store. I happened to have an old harness
Then just hook the other two HEI terminals to the coil.
Hook one of the ground/ HEI mounting screws to your ground clip (mine is green)
Branch off the coil+ / HEI connection to your battery clip (mine is yellow, 'er what I "had")
So all you do to use it is hook it to the distributor, the coil wire, and the ground and battery clips. Obviously, you can also carry a spare distributor along as well. I mostly threw this together because I ended up wanting to test fire two used engines. One didn't even have exhaust manifolds. The neighbors think I'm nuts
