Vacuum schematic help

[Rick Tuohy]

I have a 1999 Ram 1500 and I have several vacuum leaks I’m trying to fix in the AC/HEAT control - the vacuum harness is discontinued so I figured I would need to get in there and replumb the whole thing from scratch. Can anyone point me towards a schematic for the vac lines? Color coded would REALLY be awesome!!!! Thanx in advance!!!

I have been looking for a long time and have never found anything. The dealer didn't even have a schematic nor did the dealer even know there are check valves inline. I feel your pain.
