Should this be connected to something?

Yep.
One is going to the lower half of the housing in the lower left corner.The other one should go to a vacuum tree.

That was very helpful, thank you. Apparently about half of the lines have be removed or relocated over the years. But my idle went from 900 RPM to 1,200. Is that normal?

Remove negative battery cable for 10-15 min to reset ecu.

That didn't change anything.

1200 rpm isn't right. While idling idling, Pull each one off and plug both resulting holes to see which one is putting in air. Then go backwards on that hose to fault trace to find the vacuum leak. It might be the solenoid or temperature valve for the hot air system too, or just a hose or connector leak- more likely.

Before you connected those vacuum hoses...idle was ok?

I found it. Overlooked a wiring connector on reassembly. I feel stupid.

There is no stupid on this forum. These cars are like a good wife--you are always learning something new about her.
