Have a 2019 Silverado Custom and have done a ton of mods in the year I’ve had it. Fog Lights, Center Console, Steering Wheel etc. Just bought an 8” Audio Radio Control Panel on ebay from a LTZ and all the plugs fall in place except 2 which I believe are for the actual display and USB (I can listen to audio) but screen is blank and radio controls don’t work). Has anybody tried this mod or know if there is any kind of harness adaptor?
