If you have tested the red wire (the stop light switch wire) from the harness with a Circuit Tester like # PTW2979 and that wire does not have a signal, the wire on the harness has somehow been damaged. That would be the only reason there wouldn't be a signal since you mentioned checking the fuses and the connections and your brake lights working.

If this is the factory controller, I strongly recommend upgrading to an aftermarket brake controller, which are absolutely a higher quality than the factory controllers. The best option is the Curt Echo Mobile Brake Controller # C51180 because it will simply override your factory controller without having to go to the dealer to flash the computer, which can happen with wired controllers when replacing factory ones on your truck.

I have added a link to a couple of help articles on troubleshooting brake controllers for you to check out, as well as a link to our selection of brake controllers for your truck.
