MCI 9 low air pressure switch location?

Well, as long as all of the circuits on the switch are accounted for, it should work. Do you have the relay connected to that circuit in the rear? You should be able to get a replacement from Luke at US Coach? FWIW...I have a notebook with every circuit so I can remember the specifics of each for future reference.

I figured it out - this coach has a different type of pressure switch.  The internal mechanism was not making contact properly as it was out of adjustment.  I re-adjusted and now have a working low air light and buzzer.

That's great!
Before long you'll know that bus very, very well.
