Default Vacuum hose diagram

Does anybody have the vacuum hose diagram for an 88. I found a switch under the front of the plenum with one vacuum line connected and a missing hose on the other side. I have the plenum off so I want to check all the other hoses too.

Hey that looks familiar. :D '88 might be a little different, but very close. In 1988 the air control and switching valves were combined into one box instead of two.

That schematic got my azz out of a sling when I was putting mine back together. I think there is a sticker somewhere near the radiator/drivers side with this dwg. also.
