Headlights Vacuum backwards
In getting into the headlights which didnt work, I checked the vacuum lines, replaced the actuators....
Afterwards the pull down switch raised the lights, but the light switch did not...
I got access to the switch, and have a new one to install....After getting to it, I found the old switch had NO VACUUM PORTS.
In looking at vacuum diagrams, the dash switch seems be just wired series in with the pull down switch..
(Simple enough I thought)
When I turn the lights OFF, they raise, when I turn them ON, they close...
(OK, something is backwards.. Can only be 2 things right)
I switched lines on the pulldown and the switch itself...
No changes...
Lines are faded and I cant make out the stripe colors...
What the heck and I missing?
Should not be this hard... :/

The hoses on the switch connect like this:


P.S. The green-striped vacuum lines are supposed to be at the bottom end of the relays (opposite the diaphragm).
