'91 YJ Vacuum Layout

Hey everyone,
Like many others, I am having trouble getting my 4wd to engage. I have spent the last few days on my back tracing every conceivable line and am still pretty stumped. Managed to fix a couple disconnected lines in the process and got more power for it. I have managed to trace most all of the vacuum lines from the engine block to the transfer case, but I still can't seem to find one of the final connection points. Does anyone have any photos, diagrams, or schematics of the hoses coming off the top of the transfer case? Any and all help and advice would be much appreciated. Thanks in advance!

Max
