Hello!

I have to check and rebuild all vacuum lines in my 98 4WD Blazer LT. I've bought my blazer few months ago, and now I'm working on 4WD repair. I already know, that actuator under battery tray is broken (I've bought new one), but next problem is that someone removed vacuum lines to the transfer case, so I have to rebuild it. I don't have connentor for transfer case valve, so I don't know, how to connect it. There are three connectors, for vacuum, actuator and vent, but which is which?

My next question is - can I join all vents together? Rear diff, transfer case, 4WD switch and automatic transmission vent? I would like to route them high under the hood (for little offroad properties improvement) with one hose. Is it correct?

I also would like to check all other vacuum lines, but in my Chilton service manual there's no diagram - could anyone share them?

I found some old posts with diagrams, but the pictures are small as postage stamp...

Thank you in advance for your help!
