Baja Designs OnX6/XL Hi-Power w/Mode Switch 2-Light Max (355 Watts) Wiring Harness

 

The Baja Designs OnX6 / XL Hi-Power Wiring Harness with Mode Switch gives customers a complete wiring solution for high-output Baja Designs OnX6 Plus and XL-Series lighting setups. It is designed for compatible XL Pro, XL Sport, and OnX6 Plus LED lights, making it a strong choice for trucks, SUVs, and off-road builds that need reliable power and flexible control. For customers adding a serious auxiliary lighting system, this harness helps bring the main wiring, switching, relay support, and protection into one organized package.

This harness is built for two-light maximum applications and is described for up to 355 watts, giving it the capacity needed for demanding Baja Designs lighting configurations. The included splitter supports dual-light installations, helping customers power a matched pair of compatible lights from a cleaner wiring layout. That makes it useful for bumper lighting, grille-mounted auxiliary lights, chase-light positions, and off-road lighting setups where two lights need to work together.

Control flexibility is one of the biggest advantages of this harness. It allows the lights to be activated using a high beam trigger or the included toggle switch, giving customers more ways to control their lighting based on vehicle setup and driving needs. The included On/Off toggle switch handles primary light activation, while the mode switch supports dim mode control for compatible lights.

The harness uses heavy-duty wire gauge and includes battery ring terminals, relay support, sheathing, and fuse protection. These components help create a more complete electrical path from the battery to the lights while keeping the wiring cleaner and easier to manage. Instead of assembling a high-power lighting harness from separate generic components, customers get a harness designed around compatible Baja Designs OnX6 and XL applications.

With a 100 inch wire length between the battery ring terminals and weatherpack connection, the harness provides useful routing flexibility for bumper or roof-mounted lighting. That length helps installers route wiring cleanly through common truck and SUV layouts while keeping the harness away from heat, sharp edges, and moving components. When installed correctly, it helps the finished lighting system feel cleaner, more dependable, and better integrated with the vehicle.

Whether customers are upgrading for high-output trail lighting, dual-light control, or a cleaner Baja Designs auxiliary lighting installation, the OnX6 / XL Hi-Power Wiring Harness with Mode Switch delivers the power, switching, and protection needed for compatible two-light applications. Now Available at LEER!
