2017 Silverado seats
 

I scored a set of 2017 silverado seats for a local junkyard last week. Got them installed and they look and fit fantastic. The center jump seat has a cigarette lighter and a USB/audio jack. The jack part number is 13519224. I hooked a USB to the back of the adapter to see if power would pass through to the ports and it didn't. I have to assume that the input USB is for data only and not for power and the adapter is itself the power supply for the 5 vdc for the USB. Has anyone had experience with this adapter of have a factory wiring diagram for the 2017 Silverado. I scoured the web and come up with nothing.
