Noticed 3 empty ports and I have a 2018 Sierra slt with all the options except dvd screen headrest. What could they be for?


Welcome to the site. 


Going to to guess the bottom or top right could be for the power assist steps. 


Maybe the coax looking one is the forward collision alert camera if you do not have the option. 


How many switches do you have in the center console? There can be up to seven.
