This harness extends the factory 14-pin headlight connector by approximately 12 inches, giving you the extra reach needed when upgrading to High LED headlights. It’s a direct extension of your existing wiring, no splicing or cutting required.
 
Features

Retains all original pin functions with no changes to wiring logic
True plug-and-play fitment, no modification to the factory loom

Why Use This Harness
During a High LED retrofit, the factory 14-pin headlight leads are often too short to reach the new assemblies. This harness provides the needed slack for proper routing and strain-free connections, ensuring a clean and reliable installation.

Maintains all existing headlight channels exactly as stock
Does not add advanced features beyond what your OEM 14-pin system supports
