    Question o2 sensor wire assignment

    can anyone tell me the wire assignment for a stock o2 sensor on a 04 silverado 1500 5.3l automatic?
    i believe the two black wires are the heater, blue is the signal, and white is ground, but i would like to be sure. i would very much appreciate any help.
