Mine came with the truck, I would think the window would be half the problem as long as the operator not to hard to get into place. I have never lowered my back seats to look at mine. Guessing your going to have to remove the rear seats and fishing the wires to the front could be a bugger. Are you planning on using the OEM location for the switch? Mine is on the roof. Making a change for that would lower the pain you will experience with this installation. I would not go to the dealer for said work.
