Hey Randy, thanks for reaching out and providing all the details!
What you need for your 2015 Tundra is the Tekonsha Prodigy P3 Trailer Brake Controller w/ Custom Harness # TK58UR.
This kit comes with the Prodigy P3 controller along with the wiring adapter that plugs the controller directly into the OEM plug under the driver side dash of your truck.
I've attached an installation video where Rob installs these exact parts on a 2015 Tundra so you can follow along with the video when you get the parts.
Do you already have the other parts you need like a ball mount?
