Hello Jared,
Thanks for writing in!
Yes, we have custom brake controller wiring harnesses for your 2014 Toyota Tundra.
If you're looking to add a brake controller, I would recommend the Redarc Tow-Pro Liberty Brake Controller with Custom Harness # RED82CR. It comes with everything you need, including the plug-and-play wiring harness # RED49FR, so it plugs right into the factory brake controller port under the dash on your Tundra. No cutting or splicing into your factory wiring is required.
The Redarc is one of my favorite brake controllers because it keeps your cab looking factory. The main unit mounts up behind the dash, so the only thing you'll see is the small control knob. You don't have a bulky brake controller hanging down around your knees, but you still get smooth, proportional braking. The harder you brake your truck, the harder your trailer brakes, which makes towing feel much more natural. It's also really easy to adjust the braking power with the turn of the knob if you're towing different trailers or changing your load.
If you already have a brake controller and are just looking for the correct pigtail, what brand is it? That was I can find the right pigtail if available.
What are you towing that you need the brake controller?

Hello Jared, I bought a Liberty Tow Pro brake controller and wiring harness from Redarc. I tow a small dump trailer. This brake controller and wiring harness work flawlessly. The installation is easy, just pick the location you want the small knob to go. My Toyota 4Runner already had an auxiliary port for installation. I plugged in the wiring harness from my dash to the controller. The instructions and installation was simple. This controller works great. I didn’t want a big boxy brake controller under my dash. This looks stock, was easy to install and works great. I highly recommended it. Good luck, you won’t be sorry.
