Carburetor, MSD, Holley Sniper EFI questions

I had no experience with efi or Mopar ignition systems before I began my adventure. Now I have the Holley super sniper, hyper spark ignition, coil. Wiring them up was easy. I have the tanks inc tank and pump controlled by the efi. I have an internally regulated alternator . Having these pieces I was able to remove the ballast resistor, Mopar ignition box and voltage regulator. It was rather easy to do.
