It really is simple. I think you said that you are using factory electronic ignition. If so, all you need is the ECU, ballast resistor, coil and distributor.

Don't worry about wiring the " Ignition 2, start " part. All it does is bypass the ballast during cranking to ensure full voltage during cranking. As long as the battery is hot, you won't need it. But you could also just wire it to the battery while cranking and then disconnect it when the engine starts. Just don't leave it hooked up while running too long, it can heat up the coil after a few minutes of giving it full battery voltage.

If you have the single pole style ballast, just wire it and don't worry about it. And you don't have to wire the #1 terminal on the ECU. That's right isn't it? It's been a while since I wired one. Somebody double check me on that.

And don't forget to ground the ECU. It needs a solid ground.
