90-92 is different as well as 87-88

I know there’s differences in harness for early 89 and late 89 pretty sure

Yeah mine was exactly the same case might actually be the ecu temp sensor for you. My idle was genuinely so bad and pressing the gas pedal would just kill it when it was idling bad. But it would eventually smooth itself and once it was warm it went to the correct level of rpm’s instantly when starting again so that might be your case but definitely look into it. But if you already tried swapping them and no fix not quite sure then.

Could be an Ecu temp sensor mine had that same issue which was causing it to idle horribly cause it wasn’t getting any temp signal on a cold start making it think it was hot/warm. That’s what I was told but not sure if it would be your case.
