    the pic your showing is obd2a


    This article exploits a combination of ECU pin locations and wire colors for all M/T '96-98 Civic and '96-99 Integra VTEC and NON-VTEC vehicles.
    OBD2A PLUG CONFIGURATION

    Below is an example that shows the onboard (female) connector configuration for an OBD2a ECU.
    Take note of plugs: A, C, and D.
    The blank connector (B) is only used with civic/integra vehicles equipped with A/T.

    ADDITIONAL INFORMATION

    These pin-out locations were cross-referenced with OBD2a Civic & Integra Helm's service manuals.

    The information in this article applies to:

    • All US OBD2a (96-98) M/T civic ecu's
    • All US OBD2a (96-99) M/T integra ecu's
    • All JDM OBD2a M/T civic ecu's
    • All JDM OBD2a M/T Integra ecu's

    p75 was a obd1 ecu but they have them in obd2a and obd2b the best way to tell is look at the plugs and locations and you can tell the difference

    Get an obd1 p75 and you will not need to do any other modifications. That harness will plug into your car's existing wiring.
