One line goes to the bypass valve (allowing hot water into the heater core) and the other is vacuum to run all the HVAC controls from. It doesn't matter what port you get it from, it's full manifold vacuum. I believe the bypass valve one comes out of a wire bundle by the evaporator box and the other by the wiper motor.
