I'm a bit confused. I have the factory LED's that came with the truck and the dummy plug doesn't have anything connected to it. Does this mean its just extra? I don't quite understand. See my attached image. Doesn't really make a difference to me if I connect via this plug or splicing off of the wires near the stock LED's. But would be good to know why this plug is empty if I already have the stock LEDs in the bed.
