ReCurve EZQ Toyota Tundra 2014+
In the 2014+ Toyota Tundra(s), Toyota moved the power source for the front and rear speakers to an external power source located under the passenger seat.
Simply unplug the two harnesses that plug into that small power source. The ReCurve and wiring harness will make the proper adjustments. If you do not unplug the power source, the head unit will not send the signal to the ReCurve.
After removing the two plugs from the power source continue the installation as demonstrated in video.
