Are there any other ECM's that could be used with this application?
That's a trick question of sorts.
Sure you can use the earlier Mustang ECM's and even the explorer ECM but you will have to get a different harness and source a few parts such as distributor and or coil packs depending on what you use (Stang or Explorer). That's why I went with the SN95 suff. Cost me little to nothing to rework the harness myself vs. buying something plus I could reuse everything I already had.
The SD harness and the SN95 stuff (94-95) is just very close vs the earlier Stand stuff. The Explorer is WAY different than the SD harness and OBDII vs the stand stuff being OBD1. The main difference between the early Stang and the the 94-95 is the ignition wiring.
Painless sells a Stang EFI harness for use with the 90-93 Stang ECM's. It can be used with a 94-95 ECM too but you have to change a few wires and use a different distributor.
