At this point I'd be starting over trying to eliminate the variables.
I'd start with a raw (new) ignition harness.
P3690152AB MOPAR ELECTRONIC IGNITION HARNESS WITH TERMINALS ENDS AND HEAT SHRINK | eBay
Connect Light Blue directly to 12v
Connect Black/Yellow directly to the Coil (-)
Connect Green to ballast (if testing 5 pin modules)
Grind paint from module mounting screw hole, use bolt and tie directly to ground with wire.
Everything else should stay as it was (coil + to ballast)
Test
