looks like an oil pressure switch/sensor to me. someone likely replaced it, the old one fell down, and they never bothered to fish it out of the belly pan.

Definitely an oil pressure sensor, its known to commonly leak on our 545. It is located just below and towards the back of vacuum pump; not easily visible nor replacing.
Somehow I managed to install my belt without a tool. I wouldn't recommend this but I first wrapped the belt around the compressor pulley and then the unbolted crank pulley. Next (with a lot of elbow grease) I miraculously bolted the pulley on.
