Your PCM won't work.
Your '93 computer is OBD-I & the '97 is OBD-II.
You're going to need the PCM that matches the engine (which is OBD-II), or it'll never start because the engine is going to be expecting OBD-II format signals, and the PCM will be sending OBD-I format signals, and vice versa.
The PCM & engine won't be able to communicate, leaving you dead in the water.
