Vacuum Line Mystery

We have a 1994 Ford E350 Econoline Motorhome. Unfortunately the squirrels took up residence in our engine and had lunch on electrical and vacuum lines. We have been able to re-connect all but one of the vacuum lines. We have one extra line not shown on the vacuum diagram on the front of the unit. From what I can tell by the picture there are two line coming out of the Manifold vacuum tee. Both those are hooked up right, but we in fact have a third line coming out of this tee and can not figure out where it goes. We are getting desperate. Any help would be greatly appreciated.

Manifold Vac Tee is a (Coolant Temp controlled Valve) and still needs Manifold Vacuum feed from the Engine to work. There should be a port at the base of the TB or a open barb somewhere on the Intake, it might have a one-way check valve in the hose itself............

This is a little expensive compared to some but is the only one I could find doing a quick search but might be of some help and good to own in general.
