o2 sensor conversion

[G2wanderer]

I've searched and I havent found an answer to my question.

I have a 91 ls and I want to convert my o2 sensor to the 4 wire heated one. My question is will the newer o2 sensor work with my obd-0 ecu. I think all I need is the o2 sensor and the wiring to the ecu. if anyone has anymore info on this I'd appreciate the input.

no, you do this if you are going to use obd1 ecu.

OBD0 ecus can only use the one-wire o2 sensors. OBD1 ecus use the 4-wire o2 sensors.
