Missing vacuum line.
02 F150, 5.4 gas motor, about 338k miles.
Bought this truck well used so I would have a truck when I needed one. Someone has removed the heater control valve. I've got a new one, but there is a port on the top for a vacuum line, but I have no idea where this line plugs into. Any ideas or advice?

That truck didn't have a heater control valve from the factory, that's why it doesn't have one..
If you want to add one, you'll have to run an new line through the firewall and tee in to the inlet air supply vacuum motor's control line.
