Any Bonneville 94 and newer. Some 93 L27'* had them. Go to the wrecker and look for this label on the radiator support:



Not this one:



Although I don't reccommend a used O2 sensor.

Any particular reason ? The computer program is designed for a one-wire and unless you adjust the program (mainly to go into closed loop sooner), you will not see any change.

I have heard they are more accurate and it will help the gas milage and cold starting.

I can wire it in, it should be easy.

signal wire
ground (one or two wires)
heater wire (12 volt ignition hot)

Pretty much. I have a one-wire nonheated on my 93 SSEi (that'* my O2S label posted above). I get better than 30 mpg on the freeway with the modifications you see in my sig.
