Picture 1 bolts on to the compressor with the bracket bolt, it's a ground; picture 2 plugs into the head of the A/C compressor; picture 3 I believe plugs into the back of the compressor, goes to a switch that "saves" the compressor from damage in case something causes it to "superheat", like being out of freon or bearings going out.

That one piece on the end of the rubber hose is called a muffler and it does hook on to the back of the compressor. Suppose to have two valves on it though, one high side and one low side pressure for charging the freon. Many components to that system, exposure to air is not good but like you said, one of these days you might just try to resurrect it
