The 93 is OBD-I.. The 96 is OBD-II... you would have to snag the wiring harness and other electrical goodies from a 96+ w/ the 318.....
You probably could use the 93 wiring to run the motor, but the gauges and other electronics are not likely to work.
Also, IIRC, the 96+ v8's use the 46RE transmission... the OBD-I Jeeps use the 46RH..... So you might have to get a different transmission.
