That's one of the plugs for the solenoid valves on the air diverter valves mounted behind the A.I.R. pump. There should be two total in that general area. Part of the CCC emissions controls.

The green connector is the test connector for the mixture control solenoid in the carb. It is not normally connected to anything. You attach a dwell meter there to read the mixture control duty cycle when adjusting the carb.

The two-wire connectors like the one in the first photo are used for the A.I.R. diverter valves (two of them) as well as for the anti-diesel solenoid on the driver's side valve cover. I only see one of the A.I.R. valves in the photos. The other was bolted to the back of the missing air pump.

Yes. Something had to pump air into the tubes that go into the exhaust ports. The pump mounts to brackets (also missing) above the fuel pump and directly below the (missing) A/C compressor.
