I'm interested in this also. I have a set of that trim that I will be installing sometime if the future. It came with wire clips that stick through holes in the cab and doors, and the trim snaps over those. I'm not too concerned about the holes in the doors but don't care much for the holes in the rear of the cab. My idea is to use silicone to seal those unless someone here has done it and found something better.
I have a pic of a door that has the holes but would be interested in seeing the pic of the cab to see where the factory put the holes.
