I've been having a CEL for awhile indicating a bad O2. I just want to make sure I get the right sensor for the right location. As far as I know, the primary sensor (pre-cat) has a female connector on the sensor itself and the secondary sensor (in the cat) has a male fitting on the connector.

This is also to verify I have the correct sensor in the right place after returning my car back to stock.

Thanks for any help!
