Ok some of you experts help me out here.
1981. Can't get the vacuum doors to operate. I have inspected all vacuum lines and are good and I have applied manual vacuum to all lines and doors work. I replaced complete switch assy. I have vacuum to switch. What's my problem her guys?
The old switch did the same thing.

My rubber plug was bad so I cut the color coded hoses off one-by-one and plugged them onto the switch nipples. Then to make sure I knew which nipples the hoses plug onto I drew a diagram of their positions.
