I did some searching and i cant find it, and the label under the hood doest really help me...

I was wondering if anyone knew the exact routing of the vacuum lines from the tranny to manifold, or from t case to manifold, im trying to figure out my 4x4 vac problem but its not getting vac anywhere down on the drive train, so im guessing that the spot where the whole set up gets its vac off the engine is unplugged, and i dont know where it is.

 

?

 

I am having a similar problem with my truck. My 4x4 wont engage at all. I know from the transfer case the red and black lines go to the auto locking hub, and the white and green...(i think) the green goes to the manifold on my v10 its on the back side passenger side of the manifold as for the other one.. i think thats my problem.. It just ends it looks like a check valve at the end I dont know if it is supposed to hook up to anything or if it is just for vaccum release while not engaged... hopefully that helps a little and maybe someone could help me too! thanks
