headlight/vac issues
I am sure this has been asked before but I can't find the answer to my questions. I have a 1975 with a 468 in it that has a vac pump installed and now I am working through some vacuum issues. My main problem is the headlights, both sides, came up when I started the vac pump and now won't go down. What is causing them to stay up ? Could the headlight switch vac lines be reversed ? Bad override switch ? Or do I have a line hooked up incorrectly ? How can I make the headlight doors close ? Thanks in advance for your help.

Here's some great info on how our headlight vacuum system works, and how to troubleshoot it.

Just a lil ole tip I learned with hose order and an older memory.
Looking at either relay from above order is same as a traffic light.
Red, Yellow, Green top to bottom. I figured that one out all on my own
