No, it won't. The Dexter DX Series Electric Over Hydraulic Brake Actuator item # K71-650 will have a draw on the truck battery. However, how much is dependent on the truck itself as many vehicles will allow the draw for a limited time before shutting down. It's like the dome lights in your truck or your radio. They turn off eventually just like the power to your 7-Way.
