Pretty much any model year from 88-93 will work. Try broadening your search window. The computer changed in 94. I’m not sure if the connector changed.

That’s a pretty large snake you’re looking for. Is there any portion that’s especially bad or is the whole thing toast?

There are actually different ecus in the above range, with different plugs, but its all workable.

Also... I have one, in decent shape, other than age and milage...but I'm in WA, a few short hrs north of you...but if you can't find one local...
You will have to pm me to get my attention during the day though.
