Since the display on your Tekonsha Primus IQ Trailer Brake Controller # TK90160 isn't even lighting up it leads me to believe that the controller isn't receiving power. Try using a circuit tester like part # PTW2979 to see if the black wire at the back has constant power. If it doesn't that either means the fuse on your pickup is bad or the wiring from your vehicle battery to the controller is bad. According to the owner's manual you need to look at fuse 6 in the engine compartment.

Let me know if you are still having issues and I can help you troubleshoot further. I have also attached a link to a helpful article that walks you through how to troubleshoot a brake controller for you to reference.
