Need a little help here please.
The ballast / coil wiring for the electronic ignition DOES NOT CHANGE going to electronic ignition, by this I mean electrically, functionally. Below is a simplified diagram of the system. IT DOES NOT SHOW the brown IGN2 coming from the ign switch, which attaches to the coil+ side of the ballast
The wire at far top right labled "existing wire" is the blue "ignition run" (IGN1) coming from the ignition switch
IN FACT if the ECU should quit, in an emergency, you could unplug the ECU, drop a points distributor back in, and hook up the distributor wire to coil NEG. It will run just fine
