Need some help with vacuum

[stepinwolf]

A friend of mine has just purchased a C3, and is trying to figure out how the various vacuum hoses for the headlights work.

I was wondering if anyone could post a schematic or diagram that would be of help, so that he could get everything up and running.

What year C3?
As there is a difference. I found a couple sites for 68-72 and may include later years, not sure. I know 1975 and later GM went with the vacuum reservoir built into the pipe behind front bumper.

I think the only Major difference will be 68 only has 1 vacuum relay in the Front!!! 69 and after had 2!! 69-72 had a wiper door, 73 and newer didn't!!

He got it. !

A big thank you to all of you who took the time to respond to my concerns. It look's as though the diagrams I sent him were exactly what was needed to get him up and running.
