    If you just installed the Tekonsha 118701 - T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector and your brake light on the tester or the trailer it's not working.... no, you are not crazy and no, you didn't break anything... your Tekonsha red wire, is wired wrong.

    That wire needs 12v to send to the module to turn your trailer brake lights on.

    If you measure the voltage it will be... none.

    So, return, snip, reverse, solder or splice it.

    That's what she said.

    I just saved you a bunch of time. Don't be me at 3am having to go to work at 6am with the car opened all over my driveway cursing the Tekonsha in Klingon language so my neighbors didn't think I was drunk again.

    Yeah, will post nudes with the splice job sooner or later.

    ... Sh.. hhhh ttt.. I missed my exit

    I just tried installing the Tekonsha 118701 kit today on my 2019 Prius LE.... Fml

    I cannot find the place to connect the red plug!!

    I looked underneath the car and in the center towards the bumper, there is a plug that is for the rear brake lights, this is the plug that they use in the installation video for the CURT brand wiring kit, but the adapter that the Tekonsha kit comes with for the red wire is wayyy too small to fit this plug.

    I read a previous post here that the red wire plug from the Tekonsha kit should plug into the driver side brake light, but we literally spent hours trying to figure out how to get the lower brake light assembly out of the car, and can only conclude that it is impossible. The upper reverse light part is separate and easily removable, but the lower brake light piece does not come out no matter how many plastic clips I break trying to pry it out...

    Then I also read that even if I was able to get everything plugged in correctly that the brake lights will most likely still not work correctly because the pin out on the wiring connectors is wrong for 2019+ and it might interfere with the rear sensors

    If anyone has SUCCESSFULLY installed the Tekonsha 118701 wiring kit PLEASE FOR THE LOVE OF GOD help me
