Can anyone tell me which is the coil driver circuit on the black connector for the coil.

What are you driving?

It is a 93 blazer with a 95 4.3L vortec.

You likely used the coil & distributor from the '93 so... I believe it is the white wire that goes from the ICM to the coil.

Thanks for the reply. Think I have that all figured out. It has an MSD ignition. It looks like the blaster ignition went bad. It had a 5900 on it had to replace it with a street fire. The wiring is all differnt with that ignition. Going to get a wiring harness tommorow and get all hooked up. Hope this solves my no spark issue.

Well still no spark. Anybody got any idea's? Forehead is sore and I'm out of ideas.

With such a mix of parts... You probably should get yourself a good manual (FSM) and go through the wiring and troubleshooting.
