I have a 74 Dart that im removing the AC system out of. im also replacing the heater core so the heater box is out. From what i see there's 2 vacuum lines that come out of the fire wall. they were unhooked when i got the car so i don't know where they go but from what i can tell could i just remove the hose that goes to the plastic switch and just run the other vacuum line to the manifold. This would be bypassing the vacuum amplifier. I just want heat and defrost and maybe vent to work. TIA
