68 RS Camaro.
Here's what I know. My 68 has the vacuum cylinders below each headlight assembly. It has the vacuum Cylinder and switch at the drivers side inner fender. (behind the headlight) and I was told to check and it does have the original Vacuum headlight switch in it. The headlights work but the vacuum lines are not connected except to the switch. My question is how do the vacuum lines hook up to the main cylinder cannister & switch (that would be the open or normal setting switch) and then the vacuum cannisters below the headlight assemblies. I see where they hook up, but in what order or which route or should I say sequence does it need to be? And if know one knows, where could I get a book explaining this.

What it boils down to is this... I need to know which line goes in which inlet and outlet because they are not marked on any of the vacuum cylinders... Thanks in advance for your help....

There are three connections on the side of the switch. The upper connection goes to the rear of the vacuum actuators. The center connection goes to the vacuum tank. The lower connection goes to the rear of the vacuum actuators. The lines to the actuators "T" off in front of the radiator. The connection on top of the switch goes to the headlight switch. If you have a used switch you may wish to check and see if the bottom of the switch is clean since atmosphere is pulled through there during actuation.

Thumbs up

The large vacuum canister connects to the middle "Y" connection on the switch. A small hose connects to the top of the switch from the dash switch. As far as the actuators go my green hoses are connected to the front and the red to the back and the actuator switch is labeled with "R" and "G" for proper connection. The hoses route in front of the radiator core support with 2 "T" fittings( green-left, red-right if standing in the front ). I ordered a hose kit and got a diagrahm that was backwards and replumbed it by trial and error.
