I put my control junction box with the IR receiver inside the exterior light housing. Removed the bulb and connected my 12 volt lead ( I cut the transformer end off the 12 volt lead, figured out which wire was (+) and which was (-) ) to the 12 volt supply for the stock light. I ran an extension wire into the trailer using the existing hole, then along inside the cabinets and out of the trailer ( I had to drill a hole for this) and connected to the led strip. The IR receiver works from inside the exterior light cover, and I can use the stock trailer light switch to turn the led strip on or off. The led strip turns back on to whatever mode I left it in, when I flick the trailer switch.
