Plastic connector may be somewhat brittle so be careful when you remove the old sensor. If you do break the connector, it is available at ECS tuning.

Thanks, where is the plug located?

Just follow the wire from the sensor, it will lead you to the plug. It is located in a plastic housing that just snap close.

Although this video is for a 3 series, the sensor is similar including the junction box for the connector.

I think on the rear of the car the plug junction is near the wishbone control arm, don't quote me though. It's held in the wheel carrier with one hex bolt. I recommend spraying the bolt with PB blaster, and the actual sensor itself where it is bolted in. After all these years, she is sure to be stuck on that wheel carrier pretty good, you may need vice grips pulling the old one out.

Done, and done! Thanks everyone with all of the help diagnosing this. Picked up my new sensor on the way home tonight, and installed it as soon as I got home. Problem solved! It took less time to install, than I spent standing at the counter at NAPA waiting for them to find my part. Everything works exactly as it should again. Wonder how long the car will give me until the next repair? I had exactly 2.1 miles between failures this time...

Can you go back to the first post and put Fixed or Solved in the title so that people with a similar problem can find the solution.
