My older 2014 had no under awning leds at all! I added an RF Color control myself and RBG STRIP and a matching unit under carriage so one control can handle BOTH lines. Note. Do not trust the adhesive these lights strips come with. Use 3m double sided quarter inch tape to ensure they stick.
As you already have a clean factory install I would not remove it.
i ran mine down into the porch light housing using the same hole. The leds are not on that switch. The power passes into the above closet radio hole.
. Where I was able to connect the receiver transmitter to D.C. You may not have that empty box on yours as in later models they moved the DVD radio to the dashboard.
The mystery box on my older model looks like this.
It covers up the power wires to the awning motor.
Under carriage lights run only from the battery door to the rear wheel well on the passenger side.
In the case in the under lights I ran my leds thru a clear plastic hose to water protect them, sealed the ends with silicone, then used wire clamps to secure the encased hose to the side wall base trim with stainless hardware and lock tite .
You have choices. You clearly have thought them thru. Good luck and have fun.
