Hot Water Valve vacuum line?
I'm in the process of tidying up after an engine transplant.
I cant seem to find where the vacuum line to the water diverter valve does into?
I can find only one vacuum line coming from the back of the heater blower on the pax side, when i disconnect this from the vacuum tree next to the MAP sensor, the dashboard center air vent stop blowing air. So I am guessing thats not it.
Any help would be greatly appreciated.

Under the heater box, on the driver side of it, there should be a small harness comes out of the firewall - it has the wires for the blower in it - that is where the 2 vacuum lines come through the wall - 1 is for the vacuum going in from the manifold, the other will be vacuum coming out to the heater diverter valve.
