    My heater control vacuum lines were missing when I bought my jeep, and I want to correctly reconnect the control unit to the engine vacuum and the two diaphragms on the heater air duct.

    I've numbered the vacuum ports 1 through 3 on the photo below. Can anyone tell me which of these ports go to which diaphragm, and which one goes to the intake manifold?:

    Thanks very much!
