I am looking for the wiring diagram for the accent lighting on my 2015 Lariat F150. I want to add some extra RGB LEDs and have them power on with the previous lighting. On the light under the dash on the drivers side there is a harness with only 3 wires. I am only familiar with RGBs having 4 wires. Typically it is a ground and 3 live wires (red, blue, green).

I am curious how it is setup on these. Thanks in advance.
