So I need to pass emissions and I believe that my problem is that my o2 sensor is not hooked up however due to the fact that the people who had it before me cut the wire for the sensor I have no idea where the wire is to plug up my new one if anyone can send me a picture of theirs or explain what the color of the wire is that would be awesome
Do you
have the same problem?

The color is white-the O2 sensor is located on the exhaust manifold.
