Dan, you shouldn't need OBD-I at all. I'm going to be running on an obd-2 '95 ecu. I know someone with the same ODB-2 '95 I have (same part number and all) for $55 shipped. Send me a PM and I'll give you his email addy.
When Biki said it works on '95-'96, I assumed that he tried it on the OBD2 stuff, and bought the ecu accordingly.
