Hi, Bbody-philes -

My '69 Charger has the vacuum-operated headlight doors, which I like and don't plan to convert. The car has come back to me from a 2-1/2 year restoration, and with the original vacuum hoses, but disconnected beyond the firewall. I'm trying to put it back together so the headlight doors operate but can't figure out what goes where. There's not a word about the system in the FSM as far as I can see.
At least two of the hoses are color-marked, with three of them attached to the headlight switch -- two in an upper group and one on the bottom as shown in the attached graphic. The upper ones are marked with yellow and blue/green and the third not colored. These come through a grommet on the firewall in the positions shown.
Can anyone tell me where these hoses go after the firewall?

Thanks!

Mine is trouble free. Maybe easier to go with what the car was designed for rather than reinvent the wheel.
 
FSM 23-34 to 23-37 shows the system.
Thanks for that. I've never even been into that part of the manual and wouldn't expect to find the vacuum system in "Body and Frame". Anyway, it still doesn't tell me where each of the three hoses goes where it connects to the headlight doors. From the switch on the dash to the vacuum canister, the hoses are connected. Once I know how they are connected at the front, I can test the system according to the manual.

Engine vacuum goes to the storage tank. From the tank to the switch. One side of the switch sends vacuum to the pods to open and the other sends vacuum to the pods to close.

Thanks to everyone for the responses. The system is now installed and working correctly.
