    you need a 4-wire o2 sensor, and run the wires to the dx ecu.

    one wire o2 sensor is a white wire and goes directly to D14 on a obd1 ecu.

    for converting to 4 wire o2 sensor, you will need to keep this wire, and add the following:

    Grn/Wht wire - spliced into the GRN-WHT wire which is the Idle Air Temp Sensor, which also goes to D22 on the ECU.

    Yel/Blk wire - Splice into Yel/Blck wire at the firewall.

    Org/Blk wire - goes to A6 on ECU which is the Heat Control
