Can anyone help me with a schematic of the vacuum controls for a 77 with air?

 

Welcome to the Corvette Forum. I think pg can as I believe he has a '77 and has put up vacuum hose diagrams for headlites in the past.

 

Hi 77corvette and welcome to the forum.

Heres the diagram for under the hood, is this what you need? PG.

77Vette,
I am not sure how to post a picture but here is the diagram you are looking for;
go to www.zip-products.com, select your year and search for vacuum hose. You are looking for Product Number:ZAH-304 and at the bottom of the page is an installation diagram.

I just re did mine on my 79 and I had to pull the center council, golve box and the vent ducting. Only took about 4 hours. discovered that the "black" line was not connected to the headlights. If you look at the diagram that PG sent, you add a T right before the head light line goes to the manifold. If you select this part number Product Number:ZHDL-218, you will see the "T" i am talking about.

Good luck

By the way, I am finally back from gaurding the oil platforms in Iraq. Gotta love the states.

 

Welcome back! Thank you for your service.

 

No problem at all, I have been in for a little over 21 years and plan on retireing in about 4 years. I think we must have done something because when I left in August gas was over 4 dollars a gallon and now it is less that 2. I am home for a couple of months and have to go out and meet my new ship in March and but she is finishing up her deployment soon so I won't be gone long.
