Those tubes are inside the truck, you will have to drop the headliner. There should be 2 ports( one each side ) that the tubes hook to and run over to the side/rear of the body and on most cars through the floor somewhere to drain outside. Not sure if the routing has been changed over the years but the basic location of the hoses should connect to the rear corners of the sunroof. Sometimes the little nipples crack and leak as well but if removing the inner sunroof frame doesnt esxpose it then you will need to drop the headliner. hope this helps a bit.
If you can't run with the Big Dogs, Stay on the porch.
