Yamaha Headlight Wiring Harness w/Switch - Yamaha 2010-13 YZ450F

The Baja Designs Yamaha LED EFI Harness for the YZ250F and YZ450F is a plug-and-play wiring solution built specifically for riders who want to add auxiliary lighting without cutting into their bike's factory wiring. Designed around the electronic fuel injection system found on these Yamaha dirt bikes, it integrates cleanly with the existing electrical setup so you're not left improvising connections or risking damage to sensitive EFI components.

Installation is straightforward because every connector is matched to the factory harness — no splicing, no guesswork, no trips back to the workbench mid-ride. The included handlebar-mounted on/off switch keeps control exactly where your hands already are, letting you manage your lighting without taking your focus off the trail.

This harness is the right choice for enduro riders, dual-sport enthusiasts, or anyone running a Baja Designs light setup on their YZ who wants a clean, professional result rather than a tangle of zip-tied wires. If you're serious about night riding or early-morning trail starts, pairing this harness with a quality auxiliary light turns your dirt bike into a genuinely capable low-light machine without compromising the bike's reliability or resale value.
