91 Explorer PCM vs 93 Explorer PCM

[shad]

I did a 4.0 swap on my 89 Bronco II a few years ago with a 91 explorer. I think the PCM may have gone out. The local salvage yard has a 93 Explorer. Will that PCM work? Does anyone have any info as to the compatibility of the Explorer PCMs?

Thanks!

Differences are minor. If that is the problem it will make the engine run.
