A couple more wiring questions

1968 Barracuda

I'm installing my dash harness and i ran into a couple of issues. ..

On top of my heater box is this connection. ...



And here on my old harness is the plug



Problem is, my new harness doesn't have that wire and plug!
What can I do?????

Also, my heater control has this connection, but for the life of me I can't find a match on my new harness. ....



Lastly, what are these 2 wires for?



Thanks in advance!

Jeff
