my opinion is different. I have a friend that has a 97-98 ECU on his 94, and he hasnt had any problems, He swapped his because another Supra owner wanted an OBD1 so that he could have a few more things programed, versus a few things with the OBDII.
My friend knew that he want going to upgrade his computer so he did the swap. Like I said I dont know of any problems, but you might want to check further.

I agree, the wiring should be exactly the same. The only draw back is the limitations of the newer computer. Most people with the ODBII want the ODBI.
