69 Polara, in the eng compartment the PO cut the end of the vac line and plugged it, and put a manual switch where the heater temp control used to go. How do I reconnect the cable so that it's factory correct and I can change the temp from the dash controls? The cable is still there, but it's just hanging there right now

Yes, it’s a cable. I believe that iit is controlled by an actuator under the dash. The factory service manual describes..

So that switch thingy in my pic was taken from another car or something? What is in that pic that I posted? I thought mine was Jerry-rigged until I saw the same exact thing on another car at the show (the pic I posted)
Probably explains why mine is just a plain vac line with no cable thing inside it
Can I get one of those heater valves anywhere?
1970 also had the vac-actuated water valve. There are metal versions of same, in the replacement parts realm of things. Many people disliked the plastic-based OEM valves as they eventually cracked and leaked, which is why the aftermarket brands made metal ones. Knowing this, I went to an aftermarket water valve on my '70 Monaco.
The 1972 C-bodies transitioned to the cable-operated water valve as pictured. Obviously, the PO had to change the heat lever control as the '70 control had a variable-bleed vac control, or did the transition happen when the Dodge instrument panels changed in 1971?
I suspect that if you look for a metal water valve that is correct for your car, that might be the most cost-effective way to do things. AFTER you find out what else was changed to use the cable.

Watch this video:
It helped me tremendously!

Mine doesn't actually have a cable which is what confused me. It's the metal lever like the one in the pic but just a plain vac line just hanging there with a screw plugged into the end
So I should dump the lever and connect a water valve in its place ?
The car in the pic I posted was at the show, it was an early 70s Chrysler 300
Is this on YouTube? For some reason my phone won't let me watch vids in forums, says I have to prove I'm not a bot (?)

I believe that they all have it. It’s mounted on the engine side of the firewall. Just to the passenger side of center.
Perhaps you need to download the Chrysler factory service manual for your car and see what it is supposed to have. THEN you will know what you are dealing with. Easier to look at it on a computer screen than a phone screen, I suspect.
