Where are the Blunt Cut Trailer Brake and 12 Volt Power Wires on a 2011 Toyota Tundra

Question:

It has a 4 flat plug at the bumper ,and Im also installing a Primus IQ brake control. The brake control plug is at the kick panel to the left of the drivers feet,.Ive already installed it. But where does the charge wire and trailer brake wire terminate? 4 Flat only at the back side of the bumper. Any help ?

In order to find the brake output (usually blue) and 12 volt power (usually black) wires on your 2011 Toyota Tundra you will need to follow the wires that lead to the 4-way trailer connector back towards the cab while testing them with a circuit tester like part # ALL640595 until you find the correct circuits. The trailer connector you need to add the 7-way is the Adapter 4-Pole to 7-Pole and 4-Pole part # 37185 which plug into the 4-way you have now and contains the blunt cut ends for the brake output and 12 volt power wires that you find using the above method.

Unfortunately, I was not able to locate where the brake output and 12 volt power wires end on your Tundra.
