What are the most likely Donor vehicles for the A 500 4 speed automatic?

I've read references to this before--that certain jeeps had stand alone controllers and allegedly can be used for an RE swap into something else

Looks like late '93 to '95 Jeep ZJ's with the 4.0 inline six? Trick is the early '93 used an AW4 trans which is completely different.

Seem to be pretty simple to hook up if someone wanted to do an RE in an OBD1 rig.
