Okay, you say it was already electronic ignition when you got it- let's see a picture of the distributor that WAS in it. I have a sneaking hunch it was an MSD RTR or Fleabay Skip White all-in-one distributor (one wire hookup), and all the connectors for the factory ECU, distributor, and ballast were removed from the harness.
In which case you'll need to figure out what's been done to the harness, and where to splice in the harness from the new kit.
