Vacuum Lines / Diagrams / Trans & Engine

I am very curious to know where all the vacuum lines go from the back of the transmission on my 1993 Jeep Wrangler 6 cyl YJ. They were laying on the catalytic converter and all melted together. I think i have them all back the way they are suppose to be by being very careful when seperating them. But i just want a double check and cant find any Vacuum line diagrams for the complete Jeep from engine to transmission.

Also, are the vacuum lines from the transmission at all intertwined with any connecting to the engine (ie. Fuel system, etc) I am very curious. I do know the vacuum lines on the transmission are for 4x4 but thats all i know.

Anyone know ???

With the engine running you should be able to shift the 4WD from neutral to 2WD to 4WD to diagnose which line is the service, lock, unlock and vent.


These two should help you...
