If I understand what you are saying:

94-96 is OBDI harness. So you need a PCM to work with that and take note what kind of tranny. Auto tranny makes the PCM look for more stuff. Limited to mopar performance PCM from what I recall of folks around here.

Or you could go later year to get OBDII harness and associated PCM, plus an SCT tuner.

Would have to change the trans too..... OBDII expects electronic governor pressure sensor and solenoid.

@OP: Do you have the EMS already? Or are you looking for one?

I'm unsure if Holley EFI can use our cam/crank sensor arrangement.

MS3X can and is a lot cheaper.
