Is this a heated 02 sensor? If there is three wires, one is B+ for the heater circuit, ground, the signal goes to the ecm. I'm not sure which wire your talking about?

The o2 sensor screws into the manifold and there is one wire coming from the sensor with a connector at the end of the wire and I dont know where it plugs up at. I think it should go somewhere to the main wiring harness but I cannot find where it might plug into.

If it is a one wire sensor, that circuit goes to the ecm.
