The other day I discovered that the connector to my downstream 02 sensor got destroyed. I ordered the female connector as well as a new sensor and don't know how to hook the female connector to the bare wires due to the fact that the bare wires from the old female connector are colored and the wires from the new female connector are all white. Any help or diagrams would be appreciated.

    Try for free wiring diagrams. Maybe they'll show the pin-out info.

    You might be better off with the factory OEM sensor, both for color coding and for quality.
