What are these parts and what do they do?

What is this housing unit called and what does it do? The Duct Air Selector (aka A/C diverter box) mounts to it.

Same with the wire harness. What's it called and what does it do?

Thank you

That would be the heater box and the piece with the coils is the resistor for the heat/AC blower motor speed control. The wires come from the switch on the back of the dash heat/AC controller.
