This Delco electric brake controller was a perfect fit for the dash of my 2015 Silverado. Unfortunately it will only function properly if the computer has been flashed correctly during the original factory build. Mine was not. I had a trailer package, but it did not include the computer program to display electronic trailer brakes on the dash. To do this for my Silverado I must now install an aftermarket electronic brake controller under or on top of the dash so the brake settings may be read on the controller's screen. Sadly Chevrolet had done all the prewiring to accept the Delco controller, but the computer was not programmed for it. Check with your Chevy Service Department before you order this one.
