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.
