Default 4wheel drive vacuum line diagrams?

any one have a good diagram or know where to find one on the net for a 91 blazer? i found out today that there are two vacuum lines missing from where they connect to the transfer case. there are suposed to be three vacuum lines. i have one running to the actuator under the battery but dont know where the other two would go. i also have one line running from a T on the back of the motor that runs down to where the 3 vacuum lines would go but dont know which one to plug in. the third line i have no idea where the hell it is or where it went. any help or pictures would greatly be appreciated!!!

i got what i needed finally. A POSI LOK KIT!!!

after i did some testing with the vacuum lines and found out i hooked the line from the intake to the vent hose " lots of cool smoke from the exhaust from burning the fluid id assume" i decided to go the posi lok route. just need to install it now.

I installed my cable yesterday(throttle lock cable from a caterpillar impliment)but I need a cable connector for it to work right. I will take pics of what I did already and post em for your reference, I did follow a cable routing for the real posi lok and found it quite unnerving following them. I hid my cable end in the center console box so its unseen and has plenty of cable travel to lock up the front diff.
