where do these hoses go???

I looked at my 2001, and the only hose I have in that vicinity is the breather line from the front diff. It terminates behind a small plastic shield. There is a similar breather hose coming from the drivers side front axle, but mine goes forward toward the radiator. Maybe somebody routed your breathers together and joined them at that point??

Looks like trans breather(s) to me...
