i just recently picked up a 89 cherokee with the 4.0, 4.5" lift, 32" tires and my 4x4 doesnt work. i know it runs on vaccum lines and some are missing under it. there is a main one that splits off and im not sure where they go. i assume one goes the the front axle on the right side. so can anyone lead me in the right direction? thanks!

 

on the rear of transfer case by speedo cabe theres a vacuum harness check for vacuum there then check at front axle

 

ok thanks!
