WOW someone doing it right. Most want to lift than learn (guilty).

Ok first thing go here http://www.jeep.com/en/owners/ and request a build sheet.
You will need the last 8 digits of your Jeep. It will give you all the stock information for your Jeep. Important things like what axles / gearing it came with. I got mine in an email within 2 days of requesting it for PYJ.

The only one I know really well as far as Vacuum hoses go, is the 4wd one for the front axle. For most early XJ's and YJ's the front is a Dana 30 with the Vacuum Shifter. Looks like this:

Without vacuum you don't have 4WD. Also the shift fork in that can wear over time and need replaced (under $20 shipped), takes under 30 minutes if ya got nimble fingers. Fat fingers 50minutes and 2 beers.

If you dont figure it out bring it by my place (PM me), probably a cracked line or one come off. vac leaks are easy sometimes-then sometimes not.

Yeti put your glasses on next time, man that stuff is blurry LOL:D

Run to the nearest Advance auto/autozone/pepboys and grab the Haynes or Chiltons manual for your year/model Jeep. It will have all of the vacuum diagrams and is a great tool to diagnose whats going wrong.

Get the Haynes if your starting out.

With all the help I was able to run all my lines. I am down to the last ?? on this project. This thing has NO pulse Air System, It may have been removed by previous owner. Its all sealed, but how important is this to be hooked up???? Or can i just leave it ??? And i also have no idea where the Thermal Vacuum switch hook up is ??? Its my understanding that the front trap door on the snorkle runs to it, coming off a "T" from the Rear trap door. Is this correct ????

What kind of snorkel are you installing? I have the ARB Safari snorkel and don't remember hookiing anything into it. If I recall correctly, it went from the airbox out and that is it.

Plus, I am at FLW right now, but don't have my jeep. You should look into SMORR while you are here if you have not been there yet. Ghost00TJ knows quite a bit about it or you can ask TIFF

Its just the snorkle on the air filter where the two trap doors are located im not sure where to hook the trap doors vacuum lines to. Just basic no mods yet. Im not sure what the previous owner did to this and its my first jeep, so all my info is from my chilton manual and websites and i have surfed them all for hours looking for anything.
