Missing vacuum line
 

I am missing the vacuum line that goes to the 4wd actuator under the battery. I need to know where the other end of the line connects so that I can run a new line. Any help would be appreciated, pics even more.

It goes to the vaccuum switch located above the transfer case. If you look under your driver side where the transfer case is located, you will see 3 rubber hoses leading to the switch above the transfer case.

The size of the vacuum line (as was discussed on another thread) is 5/32" not 3/16". If you put too big of a hose on it will slow down the actuation time to engage the front axle. Here's the link for a little more info. Hope this helps.
