The high side occ doesn't delete the flapper unless you buy a flapper delete fitting. Otherwise, you install the "in" hose directly to the flapper and the "out" hose goes to the rear turbo outlet (unless you vent to atmosphere-then you just plug the turbo outlet port and put a filter on the "out" occ port.
