Default Replacing the o2 sensors

I'm about to replace the o2 sensors on my 2001 Alero (2.4l 4cyl) I cannot for the life of my find where the connector is for the downstream sensors. Could anyone here tell me?

You are probably going to have to backtrack from the sensor back towards the engine to find it. I'm not familiar with the Alero'*, but my Bonneville downstream sensor wire gets tucked into metal duct work that runs along the bottom of the car towards the engine. The connector is about 6 inches inside the duct work.

Thanks, found the plug, now if I could get the dang thing out of the exhaust pipe! Warmed up the car, and put some pb blaster on the bung, now I wait I guess.

Sometimes it takes a torch to get them out.
