I have a 95 2.5 ls Mystique, and it just has the two 02 sensors, one on the front exhaust manifold, and the other on the back side of the rear exhaust manifold. I suppose with the wire coming off, you could be talking about the rear 02 sensor, but it doesn't sound like it. You should be able to reach up from underneath and feel it on the manifold, helps to locate it to remove it from the top. My car only has the 2 02 sensors and the back one is pretty close to the egr tube... you could use that to help find it.
