Dash heater vacuum lines?

Does anybody know the routing of the vacuum lines from dash control to heater box under the front dash compartment?

Does the vacuum pump run? Look on the fire wall, driver side, next to the window washer fluid tank. If It is running - is it making vacuum? The Vacuum pump should start running as soon as you turn on the key.

The system was installed by the coach builder. So you might want to look up information covering the system here.
