It is an Manifold Absolute Pressure switch. Common on mid 80's GM stuff. I think they only will sense vacuum and not boost pressure but they are the same design as a Omni 3,4 or 5 Bar MAP sensor. It would be used to log vacuum/pressure in the intake manifold if you have a way to log it, say ECMLink or another tuning software that logs boost. I use the brackets off of them to mount my sensors, but have never used a GM to see if it logs any boost.

The 1222-3861 is a 3bar MAP sensor. Anything you would need to know about the GM MAP sensor can be found here: http://www.robietherobot.com/storm/mapsensor.htm

Its a good sensor for up to 28 lbs for logging, if it is a 3 bar sensor, as @Mello describes it. Nothing wrong with it.
