    I had a P3 in my 2012 with the plug adapter for it. I was going to install the P3 in my 2015 and got the ESP mount (love it BTW) but it looks like I was incorrect in assuming the plug adapter was the same. Where is the best place to get to find the correct adapter for the P3 in my 2015.

    You need to hard wire the ones with the 4.6 and no tow package

    Great info. Thanks for clarifying. What is the approximate length of this harness?...if the white connector is removed, will it reach the passenger kick panel?

    It will fit over to the connector in the panel. It does get tight, but will still reach. I am actually working on a mounting kit for the P3 for the 2007-2013 Tundra's and I am going to supply a 42" harness instead of the 30" harness that Tekonsha has. The harness will work on the 2014.

    If you're trying to mount the brake controller from the same location as the factory controller with the tekonsha harness, it will not reach the passenger kick panel. It will be too short and you'll need to extend the harness but make sure you use the correct same size wires. Especially for the power wires.

    The harness is 30" long. If you run it correctly, it will fit. I have the 3040-P in my 2014 and it is in the factory location, and I still have some slack in it. It is tight, but it fits. I am working on a new harness for the Tekonsha controllers that will be 42" long for the 2007-2013 Tundras, but people can use it for 14-19 as well.

    @Johnlakemen has the 4.6L. You need the
    $15 3031-p Tekonsha Trailer Brake Controller Harness, Compatible with Select Toyota Tacoma, Tundra
    3031-p harness that has the additional ground eyelet. That harness will not be long enough to go from factory brake controller location to the passenger kick panel where the factory connector is located in order to hard wire the controller. I have wired mine and it's not long enough. It was only long enough for me to put the controller on the front of the center console.
