78 vacuum help
I've looked at all the diagrams, but I cant find a good one that shows WHERE the vacuum lines come through the firewall. I just need to find where the source line is for the hvac controls so I can hook it up to vac. Im doing elec headlights, so I'm pretty certain the vac lines on the driver's side are not needed now, there are several coming out of a grommet on the pass side, which one goes to source? And where do the others go?

If you say I need the drivers side, which of those runs to hvac? Im not seeing that on any diagrams, but they aren't great.
