O2 Sensor question

[Cougar281]

Are all O2 sensors the same in function? The reason I ask is the 97 Lumina that I've been working on needs a new one. It has four wires and a black plug. I picked up a used on in a junkyard that has a grey plug and four wires (came off a 2003ish GM car). The plugs are the same configuration, except the grey one has an extra protrusion on the inside that prevents the black plug from working. Would the newer sensor work with the 97 PCM if I where to either modify the grey plug or swap the plugs?

What motor? IMHO I would not cut the 02 wires. They (ecm) are picky about what you do with the 02 wires. I would consider the proper replacment 02 before I'd ever cut the wires.

The 97 is a 3100. I don't remember what the newer sensor came off of. If I where to change the plug, I wouldn't cut the wires, just slide the pins out of the plug. Or modify the grey plug to remove the "protrusion".

Edit: The "new" sensor is a Denso, markings as follows:

12559850
DENSO
234000-5080
12U09

Ah nice to see another 60*v6er here. Okay in that case assuming the junk yard sencor is'nt bad you should be okay. Just do'nt cut the wires and you should be good..
