Vacuum hose for air vent

Vacuum hose for air vent
My 2013 Chevy express has bad vacuum hoses for AC vents. By battery there is 3 way T connection for the vacuum. One goes to the vacuum ball, other seems to go to the passenger side, and 3rd line goes somewhere around firewall. The line that goes to the firewall or maybe intake manifold I pulled out but can’t find where to install new hose. Does anyone know where this hose go to and how can I install it.
Thanks

vacuum is sourced from the intake manifold, and leads through the firewall to the HVAC panel (you should be able to see them under the dash on px side). Which part are you asking about?
Post your engine and maybe some photos please.

Engine is L20 flex fuel. I am looking for the location of the black hose to put it back on intake manifold. I removed old one and I am not sure where to plug new hose. Old hose was most likely already broken from intake manifold.

I couldn't find a drawing, but you should be able to follow the hissing/sucking sound. You'll probably need to remove the doghouse.
