If you know where the Airbox is with the Air Filter in it ... follow that tube to the Vortec 4200 cover. The Air travels through the Airbox into the throttle body and youll see it after removing that Vortec 4200 cover and disconnecting the tube from it and youll see the butterfly valve of the throttle body
