I have a 2014 Express 1500 AWD that used to be a CenturyLink van. There are a TON of wires in it that may or may not be original, and I've been going crazy trying to figure out wiring diagrams. Yesterday I installed a stereo/carplay system and found these in the space to the right behind the radio. They weren't connected to anything, and I didn't need them to hook up any of the stereo stuff. Can someone tell me what they are for?

there were various options available for console accessories and buttons. USB ports, inverter plugs, aux power etc.

Schematics, connector views, harness routing diagrams etc can be obtained on gmupfitter.com
