PVH solenoid hose diagram??

[windowbarn]

I'm replacing a cab on a 2010 f250 powerstroke and got everything back together basically on the engine bay except for this one hose that I can't figure out where it goes. I did figure out on all data that it's the hose for the pvh solenoid which is located on the passenger upper fan shroud. There is a rubber hose that goes across the top of the shroud and connects too a 3 way, the one hose goes to the battery tray by the rad overflow tank an I cannot figure out where the other one goes?? Can anyone please give me some guidance on this?? Thanks so much

It goes to the vacuum pump on top of the fuse box.
