On the 2014 Ford F-150, the cold side brake stop lamp switch circuit is carried by a purple/white wire. You'll want to confirm this by using a circuit tester like # PTW2993. You'll want to tap the red trigger wire from the brake controller into the brake switch wire that ONLY shows voltage when the brake pedal is pressed.
