I just joined and also just purchased a 2020 Tundra. I have a question on the brake controller. I know you are supposed to set for your type of brakes. When I go to setup and vehicle type I believe I am to push the center button to change brake types. I push it and I don’t see any type of brakes listed. Also when I go to the screen that shows the brake controller gain setting and output I don’t set a type of brakes listed as it shows in the video I watched. Do i Need a trailer connect before I can do the setup? Nothing in owners manual mentions that a trailer need to be connect before you can do the setup. Thanks for any help in advance.
