I know there are at least 10 different breather threads out there. I wasn't sure if I should add this write up to those or create an entirely new one as the method I used hasn't been widely discussed, maybe for good reason?
Utilizing the ARB kit you are supplied with 8 meters (26 ft) of 8mm flexible tubing as well as the manifold which will facilitate 4 separate connections. From there you are left to attach whatever you choose.
There is much attention devoted to the rear diff breather (for good reason) as the one way valve is positioned directly on top of the diff leaving no room for error in any kind of water fording.
I figured since I was going to be under the truck for a while planning this out and had already spent the ~$80 for the kit, why not utilize it to its maximum potential?
So I began hunting down the other 6 breathers for the truck: Rear E-Locker, Transmission, Transfer Case (2), Front Diff, and Power Steering. Without much effort at all I was able to locate them with the rear E-locker being just above the axle, mounted to a crossmember. (Pics to follow) The transmission and transfer case were sandwiched between the firewall and rear of the engine block, roughly halfway up said firewall. They are tucked in nice and tight, and for what its worth, they seem to be in a safe enough location (if you go that deep you may as well be wearing a captains hat as your truck will transform into a submarine). The front diff vents are just below the fuse block in the engine bay. Still, my OCD tells me to consolidate because the ARB breather would look so very under utilized with only one hose routing to it.
So I began pulling breathers off to find the I.D. (inside diameter) of each respective breather hose and they are as follows. Rear E-Locker- 1/8", Both vent lines to the transfer case- 1/8", Transmission- 5/16", Of the two lines routing to the front diff, one was 1/8" and the other was 5/16".
With all of that said, we have 7 breathers to tie into 4 ports.... Lets consolidate.
Within about an hour or so of googling "barb" fittings and looking at materials such as HDPE, Nylon, and Polyethylene, the consensus was Polyethylene would hold up best against the elements and the hose from ARB was made from the same material. So I began searching for reducing couplers such that the same diameter tubing could be used across the entire system. Now that the reducers were sorted, a series of tee's and crosses need to be used to join multiple lines into a single line. After all, the only material being vented through these tubes is air, and since the tubing is 8mm vs the factory 6mm I am ASSUMING the increased diameter will be able to handle the workload of multiple lines.
As soon as I have the fittings in my possession, I will document and complete the install, but thus far this is what I have compiled.

Parts list to tie it all together
Assuming all of this ties together correctly, it will only utilize 3 of the 4 available ports on the ARB manifold. However, if you prefer to keep all components that use different fluid separate, then 4 of 4 will be used and different connectors will be needed.(Front & Rear Diff w/ E Locker, Transfer Case, Transmission, Power Steering). Not too shabby.
