Baja Designs 640167 Upfitter Lock-Out Wiring Harness LP9/LP6 | Universal

Take full control of your LP9 or LP6 lighting setup with the Baja Designs Upfitter Lock-Out Harness – engineered for streamlined integration and reliable performance. Whether you're running a full LP series setup or just want better control over your backlit feature, this harness is a must-have for vehicles equipped with factory upfitter switches.

This specialized wiring harness is designed specifically for LP9 and LP6 lights to disable the default backlight function when wired to an upfitter switch panel (common on Ford Super Duty, Raptor, and other outfitted platforms). Without this harness, the backlighting on your LP series lights will always remain on when connected via upfitter switch. The lock-out harness gives you full command — so your lights work the way you want them to.
