EZ wire ignition switch with MSD (no ballast)

No it is only to replace the missing "bypass" circuit if you are not using a factory mopar ignition switch.

There has been some discussion on EFI, but when I had mine together I simply used the "usual" solution of tying IGN1 and IGN2 together, either in the engine bay or at the switch, and use that to trigger a bosch style relay which then powers "run" loads
