Harness to O2 Sensor #2 was found like this. Need to know which wire goes to what terminal of the connector. 2007 Civic 1.8 The sensor found on the lower front of the Cat, not the top.

 

 

That is the photo I've been looking for. However, I must be clear on whether or not what I'm looking at, is the right way, up or down, as it's hard to tell, due to the difference in the look of replacement connectors, vs the factory originals. Is that the connector from the harness or from the sensor? I'm using a "harness extenstion", that I bought on Amazon. It's connectors are not compatible with the factory ones, and the wire is heavier. So, I can either cut the connector off of the new O2 sensor, and swap it with the Amazon connector, or spend more money on a correct harness connector. I would prefer the later, however finding one isn't so easy.

Thank you!!

 

Its the harness side connector. Go to the junkyard and cut one off.

 

Perfect. Thanks!
