Power Controllers - Transmission Control Module, Body Control Module, & More

Modern vehicles utilize a complex network of wires, sensors, body control modules, and other components to maintain proper operation of crucial vehicle systems and functions. Vehicles equipped with a retained accessory power (RAP) controller allow some of these systems—such as windows, door locks, headlamps, and radios—to remain powered on for a limited time after the ignition switch is turned off. But why should only late-model vehicles have all the fun?

Summit Racing’s extensive selection of aftermarket power controllers - transmission control modules, body control modules, or powertrain control modules also make equipping your resto-mod ride with modern comforts a breeze. Whether you’re implementing retained accessory power on a vehicle for the first time or need a replacement for a worn-out module, we have what you need to get the job done. Turn off your engine, flip the radio on, sit back, relax, and order yours today!
