2000 Venture there are 5 vacuum lines going to the HVAC controls. Does anyone know the color of the vacuum supply line. Does this run to the engine

 

I cut the bundle open and traced it back that comes through the fire wall. The Vacuum line runs under the washer solvent bottle. I found 3 holes in the line. This line does terminate in the intake right next to the Alternator. I replaced the line and my HVAC control in now working again.
