ABSTRACT:
A towing and brake circuit includes a power source and a switch electrically connected between the power source and a park brake solenoid. A flasher module is electrically connected to the park brake solenoid. A unidirectional current controller may preferably be electrically connected between the park brake solenoid and the flasher module to electrically connect the park brake solenoid to the flasher module. An engine oil pressure switch is electrically connected between a power source and the park brake solenoid to flow current from the power source to the park brake solenoid when engine oil pressure is generated.
