There's supposed to be a black little plastic hose sticking out by where the heater hoses go through the firewall. That line runs to a 3 port check valve. The side on the same side as that little black line goes to a vacuum reserve ball behind the passenger fender. The other side of that check valve runs to that AC spot on the vacuum tree.

I have a slight sag in my rear
See pictures below....
The AC line from the tree traces along the firewall behind the upper intake and connects to a plastic check valve as Described in the above post. I hope these pictures help.
