Thread: 95-97 2.0 rear o2 sensor wiring

Thought you wanted to put a 3 wire O2 sensor in? The 4 wire you have, is it still on car or is it a new part waiting to be put on?

im going to merge 2 sensor pieces together..

bought new sensor but using plug off old sensor..
get what im sayin now? haha

not modding any part of the harness on the car..

i need to do this anyways..cat is farther down the exhaust than the OEM location..this is because of the hotshot header..OEM cat in my car is ~2-3" off the engine..lol

Gotcha.

Look at red box. This is diagram for 98 1.6 rear O2. F25 connector is harness on chassis side.

B is black right..and Bl is blue..
i dont have any brown wires! i have a green one! ugghhhhhhh

Color listed in diagram is on chassis side of harness. You will need to match up the F25 connector with the O2 sensor you have.

posting a pic of what i have to work with..uploading now..

of course it is..i am a ratard! lol

ok, so the diagram orientation is me as if i am looking at the actual pins themselves on the chassis right?

Yes, just match it up to O2 sensor.
