You may be able to swap the harness, add the necessary parts, and make it work, but the '93 is Speed Density, the '94+ is MAF. I have a '93 parts car, if you are looking for an ECM, let me know, I will sell you mine. If you have a '94 PCM, I'd be willing to trade.

Im trying to get rid of the 93 pcm ..make a long story short. I t56 swaped it and already have software for 94 pcm.was just trying to avoid getting new cables and tuning software.

I have wondered about this too since I do have a complete parts car that is a 97, 97 would probably be a different animal tho from the 94?

Ya 97 is obd2. 94 is obd1.... More thanks would need to be changed like the timing cover.
