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
