Only two ports to plug-in were underneath the console . One the main one that I plugged in under passenger seat and the other one is the one in previous picture. I took too of the console apart to see the wiring just in case I missed something but all the ports as you see in the new picture are accounted for and the single wire going towards the front is ending in the charger like port . I’m puzzled as well but this came out factory Silverado without any modifications.
