Hose next to radiator - Passenger side - HELP
 

I was trying to locate the low-side pressure port in order to recharge my A/C and I think I found it next to the radiator BUT also noticed a hose that is not connected and I am wondering what it was.

Could anybody tell me if #1 what I am showing in the pictures is the low-side pressure port to re-charge my A/C and #2 what is that hose or where it is supposed to be connected to? THANKS IN ADVANCE!!!

I just found out that the valve/port in the picture is the actual lowside pressure port. So thats 1 question less.

I still dont know what that hose is and if its supposed to be like that. Anybody?
