Default Help with identifying parts

Fellas, any idea what these parts are? 1980 corvette with air pump removed. Second picture is like a diaphragm under the exhaust manifold (on passenger side near spark plug wire 8 and 6 with rubber hose connected to it. third picture connection goes into. I did some research, first pic is EFE TVs switch connector and next picture is hear riser? Is the heat riser needed? Thank you.

Did you ever get an answer on your question about what the part is in your first picture? I need to replace a couple of those, but cannot find them, and do not know what the proper name is. I'll need to rig something in the meantime, but if anyone can give me a part name or number for these TVS connectors, I would appreciate it.

no didn’t get any answers. It’s heat riser diaphram. I disconnected and cap the port on the valve. Using electric choke and never had any problems since capping the valve and warm ups in winter is fine.
