WAS WANDERING WHICH DIRECTION DOES THE KICKPANEL INSERT GO. LONG END WITH LIP TOWARDS HEATER BOX OR SHORT END TOWARDS HEATER BOX? WAS THINKING SHORT END TOWARDS BOX AND LONG END TOWARDS FENDER TO PREVENT WATER FROM COMING THRU? THANKS IN ADVANCE!

The inlet hose flange is meant to attach to the heater box, and the other round hose side to the existing round collar at the passenger kick panel. If you need a second flange and collar for the kick panel side, you would have to get another kit, with the hose and flange/collar assembly and adapt or mount to the kick panel.
