I’m having trouble finding any info on where the brake wear sensor harness leads to on my 2021 Chevy Silverado,does it tie into the main harness or does it clip in somewhere else? My clip that the sensor slides into is broken and I can’t find a replacement for it yet.

 

I am going to say that because it is a 2021 model year vehicle, you are going to have to get one from a dealership's parts department. That is still a new vehicle parts wise and the aftermarket replacement parts are just now starting to come out, but in checking rockauto.com, I do not see any aftermarket brake pad wear sensor mating connectors.

You could try looking it up at the ACDelco/GM Genuine online parts catalog at http://parts-catalog.acdelco.com/acesCat.php before going to a dealership.

Good Luck!
