I am trying to figure out where to hook up the vaccum lines from the ZL dash to the engine bay to control the direction and temp. mix.
I have looked at the diagrams in the Max Ellery books for both types of car but can't seem to match any thing up. Does anyone know how to figure this one out?

the ZL have a vac. reservior under the wiper scuttle panel. the main vac hooks up to that

Thanks. I will try and get to that this week.
