Where does o2 sensor plug in at?

Where does o2 sensor plug in at on a non-turbo 420a motor? I can't fing find it.

If you mean where along the exhaust it goes into, you can actually see it along the exhaust manifold under the hood. If you are looking under the hood, it is on your left hand side about half way down between the heat sheild and where it curves under to the bottom of the car if I remember correctly. Does that make sense?

are you looking for the up stream or down stream O2 sensor??
