    I swapped a JDM D15B (B16Z6) into a 93 hatch. I bought a 4 wire O2 sensor and P28 ECU. Car runs fine but I need to wire up the O2 sensor.

    How do I run the 4 wires from the O2 sensor?

    Thank you.

    Since your in a OBD1 car you should have a plug already for a 4-wire O2 sensor. Just plug and play.

    Wiring Harness

    It won't plug and play because I am using the original wiring harness for a CX that uses a one wire O2 sensor. The engine was swapped to a JDM D15B and the ECU was swapped to a P28.

    Really! I thought all OBD1 cars came with 4 wire 02 sensors. I've done a few swaps and never ran into this problem of a single wire 02 on a OBD1 car? Strange. Well your going to have to find out from the ecu pin out where the other 3 wires are from.

    Wire match

    I was hoping someone had figured out the sensor wire color/ECU pinout match...
