you have a actuator valve under neath your battery box. this actuator actually pulls a cable to engage the fron diferential. it runs of vaccum. now on top of your transfer case there is a 3 way vaccum switch. one vaccum lines run from your intake to the switch on the transfer case. th other vaccum line runs from the actuator under your battery box to the other vaccum prong on the switch on your transfer case. or you can just run a vaccum line from the intake to the actuator under your battery box. this is the short cut method.
