ac heater control valve

hey all, I noticed that the heater control valve has a barb with no hose hooked to it . I do not see a hose around anywhere and am not sure where the control side is or where it supposed to attache to. All data doesn't show me anything and doing searches shows different valves. Im wondering since my truck is a half year it could be the reason for a different looking part . Could explain why max ac inst much better the regular ac haha.

my truck a 2003 7.3 4x4.

thanks in advance for any help

looking at it last night, the vacuum lines run off the vacuum hub switch and one line run towards the back over the fan housing which I believe is for the recirc door. should there be a T in there on line to run t the valve ?
