According to the Toyota Electronic Parts Catalog:

89661-2B840 is for ST205 made from Feb 1994 to Mar 1995

89661-2B841 is for ST205 made after March 1995

I don't know what electronics might have changed (if any) during that time. If you want to play it safe, buy an ECU that is a direct match for your original.
