Power steering fluid leak

My 1998 Sable is losing power steering fluid. I finally bought some dye which I poured into the power steering reservoir and tracked the leak to what appears to be a sensor near the firewall on the driver's side of the engine compartment. It has a two-wire connector on top of it, and as far as I can tell, the leak is coming from the base of the sensor, though it doesn't feel loose. What is this sensor, and can I just replace it and not the whole assembly it's part of?

Does it look like this? That's a pressure switch that is available separately.

I just found this topic through a google search on a power steering problem I have on my fiancee's mother's mercury sable and was hoping that you guys could answer me. I am having the same exact issue mbongiov was having even AFTER replacing the power steering pump and pulley. This might be the final solution in fixing this problem. Do you have a picture or diagram on where this is located? I could not for the life of me find it while doing a search behind the engine. Thank you so much if you can help me!
