Replacing O2 sensor on '92 200

The one thing I haven't done on my '92 is replace the 02 sensor, it appears to be a three wire sort that is mounted way under the car. So my answer is this, does the new unit come with all that wire or shall I just solder in a new sensor down there?

It depends on how much money you want to spend: ~US$50 for a generic with soldering, or ~US$200 for the exact fit.

Are the generics one or three wire? I've seen bosch one wires for 20 bucks.

Either. 3wires are more.

The three wire has a pre-heater. It costs a lot more than the single wire.
