Heat/AC vaccume lines

[weldedrail]

I need to hook up all the black rubber vacuums lines to the back of the control unit on my 70 dart swinger. It has AC and I hav installed a new vaccume switch, just need a picture or a diagram of where the lines go. I hooked them all up in no apparent order and I have defrost when you push max AC.

You should have a moulded clip like what I have pictured, if it's been cut, I'd recommend going to the junk yard and getting another. I didn't mark mine when I removed the a/c box, so I'm hoping the length of the hoses will tell me what they hook up to. I think there's 3 actuators on the box, one on the heater hose, and one hose to the manifold vacuum fitting.

factory service manual should have the diagram for that. Manuals on cd are available too.

Mine must have been cut at sometime. I guess I will need to get the factory manual.

I don't know if this will help. It's from my 1968 Plymouth service manual for Valiant or Barracuda.
1970 may be different.
I shows what line goes where. It might give you some idea.
A manual for your car would be of better help.
