    02 pinouts?

    hey guys, Any body have the 02 sensor pinouts? On the actual engine harness, not the sensor... My truck runs real bad once it warms up, runs rich as hell, .. So I think maybe harness is not pinned right. the 02s are new ac delcos, and the MVs dont fluctuate on CLosed loop..

    Thanks
