If you have the towing package and the factory 7-way at the back of your 2015 Tundra, the correct plug-in harness for your vehicle is the Curt TriFlex, part # C24VV is part # C51455. I have attached a photo of the location under your dash where the plug-in adapter will be connected to. I have attached an installation video for a brake controller on a Tundra that should be very similar to yours.

If you do not have the factory brake control wiring harness port you will need to hard wire the brake controller by splicing into your Tundra wiring. The harness for this is part # C51515.

If you do not have the towing package, you will also need part # ETBC7. This gives you a 7-way connector at the rear of your vehicle. I have attached some links to helpful articles you can check out.
