UPDATE
Rear diff, Front Diff, Transfer-case, Auto-trans have Diff Breathers With hoses already connected.
Rear diff-breather is on the passenger side and runs to the drivers side chassis,
Front Diff-breather in on the passenger side and runs up into engine bay, but not very high.
Transfer-case and auto-trans (also has a 3rd breather coming from black box at rear of transfer case) breathers run along (3lines) transfer-case, along auto-trans and up onto back of engine block, again not very high.
I will be extending these lines much higher as i know i have been in deeper water to where these breather lines are..
