1996 ranger vacuum hose diagram to the reservoir and inside vehicle

[franko0_2]

Could anyone direct me to the vacuum line diagrams for the heater controls and to the vacuum reservoir on a 1996 ranger 4.0 ohv? I have looked and I can't seem to find them. I need to change my heater control valve (leaking) but there is no vacuum to it and it doesn't move. I probably have a broken or disconnected line somewhere but I have no idea what I'm looking at. I would appreciate any help you could offer.
Thanks in advance
Frank

Looks pretty simple. Usually there is a supply hose that is dry-rotted out under the hood. Those plastic lines crumble after years in the heat.
