Question O2 sensor?

My car is running rich and the exhaust pipe is fairly black. I don't know if the O2 sensor has ever been changed, but I would like to give that a try. I am not getting any codes and I can't find a parts house that carries anything other than the single wire O2 sensor. I haven't tried the dealer yet, but that is almost always my last resort. Would the single wire sensor work? I know it would have to depend on the engine getting the sensor hot instead of the other 2 wires, but I don't know which wires not to use and so I am reluctant to try the single wire.

Anyone.........
