Electronic Ign/Hei/Ballast Delete Wiring?

I put my ignition system behind a relay.
But I also used a GM HEI module and an MSD e-core coil. No ballast resistor in the system.
Also I installed a '90s (Ford) alternator so I'm not using much of the original chargingsystem anymore.

Will be installing a MegaSquirt ECU these days to be able to tailor the ignition curve better, and control fuel later on.
