E-Locker Harness Kit Universal

The E-Locker Harness Kit Universal from Dana-Spicer is a complete electronic locker wiring solution designed for off-road enthusiasts and 4x4 builders who demand lockable differentials on challenging terrain. This harness kit bridges the gap between your vehicle's electrical system and an electronic locker, providing the control interface necessary to engage and disengage locking functionality with precision. Whether you're tackling rocky trails, deep water crossings, or sandy desert runs, a properly installed electronic locker harness transforms how your axle distributes torque to the wheels.

This universal design accommodates a wide range of Dana and Spicer axle platforms, eliminating the need for vehicle-specific variations and reducing inventory complexity for shops and builders. The harness integrates solenoid actuation with switch-activated engagement, allowing you to lock the differential on demand while maintaining conventional open-differential behavior on highways and normal terrain. At 1.48 pounds with compact dimensions of 10.55 x 3.25 x 11.1 inches, the kit ships ready for installation with all necessary connectors, relays, and wiring pre-assembled to OEM standards, significantly reducing installation time compared to field-fabricated solutions.

This harness kit is ideal for expedition builders, rock-crawling competitors, and serious 4x4 operators upgrading Dana 35, Dana 44, or Dana 60 axles with electronic locker differentials. Installation requires basic electrical knowledge and compatibility with your vehicle's 12-volt auxiliary circuits; professional installation is recommended if you lack automotive electrical experience. The universal configuration means cross-compatibility across multiple platforms, making it a smart choice for builders who maintain or swap axles across different vehicles. Verify your specific locker model and vehicle electrical architecture before ordering to ensure seamless integration.
