Description
Upgrade Your Halogen to OEM LED the Right Way
This is the required plug-and-play harness when converting from factory halogen to GM OEM LED headlights on 2019–2021 and 2022 Limited Silverado 1500 models.
Designed to support both styles of GM LED headlights, this harness enables the LED accent strip to function as your daytime running light, while preserving full headlight operation at night—just like factory.
Important Note: Some aftermarket or surplus headlights may come with the wrong control module. Make sure the module on the back of your LED headlight says “Silverado”. If it doesn’t and you run into issues, you’ll need to swap it out with the correct GM factory module.
