vacuum diagrams

does anybody have a diagram of the vacuum lines on the engine side and the ac side?

i'm currently chasing a lean code from a vacuum leak (and high fuel trims) and couldn't find any on the engine side, the ac controls were not working too due to no vacuum.. I guess I might have a leak inside the cab..

How are your power brakes? Check the big connector behind the throttle 90degree elbow. It will rot and crack. I'm looking to replace mine before I put the intake back.

found the issue and my ac controls are back (mode selector and temperature control - actuator for the coolant bypass valve)
there's 2 cracks on the hose near the tee going into the climate control, the first crack is obvious but the 2nd one which took a while to find. Bought a vacuum hose coupling set for $4 to fix the crack.
