Hey Dennis. For your 2023 Toyota Tundra, you'll need the Redarc Tow-Pro Liberty Brake Controller w/ Custom Harness item # RED98CR. This is the correct kit that comes with the custom fit wiring harness that will make installation super easy.
The brake controller port on your 2023 Toyota Tundra is located under the driver's side dashboard, behind the lower kick panel, near the emergency brake pedal. It is a white 10-pin connector taped or plugged into the wiring harness.
What kind of trailer are you pulling?

Hello Dennis : Absolutely love the controller. I carry 4,000 - 5,000 lbs of logs on a 14 foot trailer and I can adjust it to stop perfectly matched with the truck. The only down side is a problem created by Toyota. Their wiring harness is buried to high up in in console it took me HOURS to find the plug. Literally, if you can find a blue cable - keep pulling !!!!
