can i use a 94 computer/harness in my 93

[manfred717]

Is it possible to use a 94 computer and harness in my 93. It would make my life so much easier, because I am not fond of the chips nor chopping my harness for a heated o2 conversion plus I already have the o2 extensions and o2s for a 94+.

You need the harness pcm new o2' sensors 94 Idle air control ( the whole bottom of the tb) and a different oil psi sender.

Unless you are planning on running in Speed Density mode, you'll need a MAF and the supporting duct work. You'll also need the pair of fittings so you can mount the new oil pressure sending unit up on top of the block behind the intake, and the plug for the hole in the side of the block.

You don't need to change the oil pressure switch location. Just extend the wire, no harm will be done. I did this swap and it is a lot easier than most would think. You just need to switch around a wire or two, get a 94 pcm/harness and change some sensors. To the original poster, PM me if you want more details on how to do it (including wiring for serial signal data wire and stuff).
