The PET # 928 573 096 03 identifies it as a "A/C valve" sold on Pelican:
Pelican Parts - Automotive Parts and Accessories - Porsche & BMW Later cars only have the lower "(freon) AC pressure switch" to the right in the photo. Pelican Parts - Product Information: 959-613-137-00-M212 I tried to trace the wires in the WSM early electrical but did not find it listed or where the wires attached went. Maybe just a dash lamp showing AC ON/OFF. An AC pro on the board will know. J_AZ

ok. Thanks for the information.
I think it may be high-pressure safety switch. This is the electric wire diagram AC of 944 Early 84' like mine. Why not this high-pressure safety switch appears?  And I do not know how to connect electric circuit. |

That isn't OEM to an 83 car, might be for an 84 though, however, that's where the high side pressure port is. My guess is it's a high pressure cut out switch, but that switch doesn't need to be there (and you don't want it b/c you can't read the high side otherwise) if the pressure switch that John mentioned works properly.
