EJ20G TWO wire O2 sensor

AsphaltsCry · 03-29-2005, 10:49 AM

so i have a 95 WRX RA motor. I got the rear O2 sensor plug with the front clip, but it was cut before the sensor. Nobody stateside has ever seen a 2 wire sensor. There are one wire sensors, which is just the O2, and 3 wire sensors which is O2 and a heater, 4 and 5 wire sensors also. which are usually heater, O2, and AF. Does anyone know what the deal is with the 2 wires or maybe what would work as a replacement.

95 WRX should not have a rear O2, it has a rear Exhaust Gas Temp. Sensor.
