What's this hole on my firewall for?

I'm not real sure of what the other end should look like. Sometimes it's a coil, or maybe it's just the tube itself, I don't know. It goes into the airflow past the heater core (warm air) and it serves to regulate or let's say "fine tune" the heat. I am pretty sure it's a tube though.
It may be OK although it looks bad in the pic.

Judging by bulldog's pics, I'm missing more than just that.
If I understood that dual core system, I could probably just eliminate everything and just put in an external valve on the wheel housing (where they belong, dammit! Lol).
Googling showed me that these Chrysler heater control valves were prone to leaking and many owners simply ripped them out.

I can't tell but yah, something...
I see some kind of sensor. Was this an ATC car?
The black plastic unit (circled in blue) with two spade wires going to it (a little hard to see) and the rubber hoses going to it and one U shaped rubber hose that goes from one part of the unit to the other is usually found on all a/c equipped cars with a/c but without autotemp. It is used to turn on the a/c compressor during hot restarts so that if someone turns on the a/c on a humid day, the moisture in the a/c system vents will not immediately cloud up the windshield if either the a/c or heat is activated by the driver. This switch allows the evaporator to cool down quickly so that moisture in the blower air will not affect vision. If it is working properly, on a hot restart, the a/c should come on and then shut off automatically after a few minutes. They are found on most all fuselage cars at least on the right side of the a/c/heater evaporator/heater core unit underhood fiberglass cover. On your slab side car, it was placed where bulldogchesty shows in contrast.

Hey Bulldog, can you see where the copper wire that travels off to the drivers side goes to? I need to see where it ends up and then I can look at all the airconditioning parts i have here to see what goes with that valve, i may have that curved plate floating around too.

It takes my mind off other things that I don't want to think about.

on the 67 Newport:
That is for the 4 gauge power lead to the 3000 watt amp under the passenger seat, for the 15's in the trunk. You may want to consider installing an extra battery in the trunk with a couple of capacitors, you don't want to starve the amp!! Also, a 135 amp alternator is never a bad idea. Don't forget to install a grommet before pulling the wire through, a dead short in a 4 gauge wire is not pretty!!!

Now that freaks me out. I'm definitely missing something important then.
That pic looks familiar! Your system is missing the Heater Control Valve.

Is that not the hole where the tube goes thru for the portable urine jug, for those long 2 coffee rides without rest areas ??? :coffee2::coffee2:

I agree, that is/the drain for evap. Usually there is a rubber tube with a 90 degree bend to let the condensation dribble out.

Nope. After a night of "research", it IS for the heater core valve.
Now I gotta find all the thingamabobs, doo-hickies, and what-nots that the ******* ripped out from under the dash. Grrr...
I'm just going to look for an entire complete setup.

Out of the seven previous owners, I'm pretty sure it wasn't him.
He had it less than a year.

I might have the whole set up for you. It depends on what the previous owner removed.

Sounds good, Bulldog. I wouldn't mind a ride to PSL in the near future.

And I was wanting to take a ride up to see you also. We need to get together to help with what you need.
