i just got a o2 sensor from a 92 nissan 300zx need help

[silva180sx1515]

does any one know if the wiring of the 02 sensor has to be changed and if so to what and how, i have a redtop sr20det. it's a bosch 02 sensor from autozone

you just pull the old o2 wiring pin out of the harness and and put the 300zx one in, they both have the same color white, black, and red. Remember the order on the harness before you pull it out so you dont mess up.

From what i heard the 300zx o2 will make the sr run rich, use the second o2 from the KA downpipe. Same 3 wire sensor.

[silva180sx1515]

the wires of the o2 are two blue and a black, that's why i'm confused

Thats weird, I have the Bosch 87' 300zx o2 also, the wire color is the same with the SR.Is the part # 13385?

mine is off a 92 it's the fat o2 sensor, i just got a megan racing turbo extension so i needed a fat o2 sensorit's actually two black wires and one blue.

take it back and get a 92 sentra se-r 2.0L o2 sensor, its the fatty.
