What is this?

Hello everyone I am in the process of rebuilding my a/c box out of my 1968 GTX and I have a little doodad in there that im not sure what it is or if its needed or if i can get another one. here is a picture

I assume its a temp. sensors to prevent ice over. but where did the end of the wire go?

its also worth noting that i have a Classic Auto Air engine compartment upgrade kit and a march performance serp. kit

no? well riddle me this. i am trying to remove the evap and it looks like the two drain lines have large disk soldered on it and is preventing it from being removed. what to do?

it kinda looks like a blower motor resistor to me but not really sure.

Thank you! now do i need it for the a.c to work? because its clearly broken off the heater valve. also what is the proper heater hose routing?

 

[ScottMH]

also, somewhere along the line the wire to my a/c clutch was cut and stuffed. so were does it orginate so i can run another wire.

if anyone has a wiring diagram of the a.c system that would be great
