Simplify aftermarket accessory wiring in your 2024 and newer GM HD with the AEV Auxiliary Switch Harness. Designed for trucks already equipped with the factory auxiliary switch system, this vehicle-specific harness provides a clean, plug-and-play solution for connecting compatible lights, compressors, and other powered accessories.
The AEV GM Auxiliary Switch Harness utilizes all five factory auxiliary switches and features OEM-grade wiring with custom-fit routing for a clean, professional installation. Convenient under-hood connection points make it easier to add accessories without creating a cluttered engine compartment or relying on a universal wiring setup.
Rated for up to 30 amps and equipped with built-in voltage protection, the harness provides dependable power distribution for compatible aftermarket equipment. It also includes dedicated open wiring for adding a trailer brake controller to vehicles that were not originally equipped with one.
