To use the Pollak 7-Way tester part # PK12741 that you have to test the brake controller of your vehicle will require a buddy to press the brake pedal of your truck to see if the voltage from the brake controller makes it to the tester and lights up the correct LED. Also have them use the override handle of it to see if that lights it up as well.
