When installing the trailer wiring harness part # 119178KIT that you have the red wire gets ran to the stoplight circuit. If your vehicle has taillights that only come on with the brakes (and not with the blinkers), that is the circuit this should run to. Another place you can find this circuit is the third brake light of the vehicle.
