    WHT - WHT/RED wire goes to D14 which is O2 Sensor Input
    BLK - ORG/BLK wire goes to A6, which is Heater Control
    GRN - GRN/WHT wire goes to D22 which is Sensor Ground
    BLK - YEL/BLK wire goes to A25 which is Sensor voltage (you can also splice into the power junction harness at the driver side shock tower harness)

    but you wouldnt want to do that unless you have the si/ex etc ecu....otherwise it ownt read it....just return the O2 and get the proper one for your car

    cx has a 1-wire 02 sensor.

    use the amount of wire o2 that your ecu calls for (you don't specify in your post)
