    I have, what was sold to me, a PR4 OBD1 ecu too and i was also skeptical...i posted a question here and the answer i got was to see if it has three gray plugs (on the ecu in the auction) then it is OBD1
    hope that helps ;)

    Then it is OBD I, OBD 0 has two, a green and grey, and OBD II(B) has four.

    I thought that the obd0 ('90-91) had a window with a LED on top of the ECU housing for the error codes. The obd1 ('92-93) has a remote plug for a jumper. Is this correct?

    Also, this image depicts the differences between ECU generations. From top to bottom: OBD IIb, OBD II, OBD I and OBD 0.

    92-95 have a seperate jumper that displays in the CEL.
