Ok, I have a new o2 sensor and need to know where the plugs are for it.
Under the passenger side front mat is the 2 plugs that look like the same ones on the sensor.The harness goes forward toward the firewall, not back toward the sensor. Is the harness that long? Has anyone r&r this sensor before? thanks.

Yes, You simply disconnect, remove the weather plug and pull the wire through under the car. Install new one, fish wire through the hole and connect to the harness. This harness wire runs to the control unit(Motronic). This is one of the easier D.I.Y'ers...
Good luck, use a little liquid wrench for stubborn sensors.
