I have a 2017 Chevy Silverado crew cab LT model and it didn’t come with the trailer brake control module on the dash but I added it and it was a plug-in play and it’s not working. Everything else is working the brake lights do and the blinkers does computer need to be flashed or turned on or I have no idea someone please help. I have checked the harness. It’s in good shape. Everything looks right and all of the fuses are in the right places.
