What is this connection for

I recently just purchased a pretty decent 1990 gmc k2500. And I'm trying to fix my a/c system.

Trying to figure out what this green connection is for on the back of the ac compressor? And where the wire that use to go to it, might be routed. This is the third motor that has been placed onto the vehicle, and it's hard to know what is missing.
