What is this small hose dangling underneath my TJ?

2003 Sport, 4.0.

Noticed when I got to work this small hose with a light colored plastic connector on the end just hanging loose under my passenger side. Right in front of the center skid plate.

It drives fine, no CEL, nothing dripping from the hose. But I don't have time to crawl around underneath and check it out, so I hoped someone here could ID it.

Hopefully the pic attached, doing this from my phone.

Perhaps the cowl drain hose. More likely the breather, though. I wouldn't worry IMO. When you get a chance, follow it back to its source.

From the location of it, it appears to be your transfer case breather.

Thanks guys, transfer case breather makes sense, that didn't even occur to me.
