My original plan was to put the receiver in the slide but I felt there wasn't enough room for it. I ended up putting it behind the control panel, bypassing the switch and wiring direct to the receiver.
However with the other lights tied into the reading lights one may have to disassemble the reciever to make it smaller. That should allow it to pass through the puck light hole and fit between the ceiling and roof. Of course the receiver could always be located off to the side with a little clean wiring.
