Expert Reply:

You are correct that GM changed the wiring to the 7-way connector on the 2019 and newer Chevrolet Silverados and 2019 and newer GMC Sierras. We have run into some customers that have had issues with getting the trailer lights to work properly, but this is usually when the trailer has LED lights.

If your trailer has LED lights then you will need 7-Way Trailer Adapter for Towing Trailers with LED Lights # C57003 which has built in load resistors to trick the towing system into recognizing a trailer and sending proper voltage to the lighting circuits.

I included a video of the # C57003 for you to take a look at.
