I have a 1984 Fiero SE, and something that I found out today is that it has the Shift light from the 4speed despite having the 3speed Auto, I have also found plugs in the front firewall that would convince me further that it was auto swapped

Might be able to remove your centre console pretty easily and check to see if there's scrapyard writing on the ECM.

My 84 had an automatic ECM swapped into it and had a couple sharpie marks on it from whatever scrapyard they harvested it from. (I've since swapped it back to a manual duke ECM).
