    There is a jumper under the passenget side dash for checking ECU codes. Put a paper clip in it or some sort of jumper wire.

    90-91 PR4 = OBD0 B18a LS motor in Integra (LED inside the ECU)
    92-93 PR4 - OBD1 B18a LS motor in Integra (Need to jump the service connector under the passenger side dash)
