Venoms Auto Fog Light Harness is designed to fit the 2021-2024 GMC Yukon.
From the factory, GM disables the fog lights when high beams are engaged. This harness overrides that limitation, restoring full fog light functionality for improved visibility in all driving conditions.
All compatible models and installation diagrams are provided in the full product description below.

Our Auto Foglight Harness will allow you to always have your fog lights on anytime the headlights activate, regardless of light settings you have selected from inside the cab. Our harness bypasses GM’s LCM tuning to automatically turn the fog lights on. This means you will never have to turn them on manually again. This will keep your fog lights on even if you activate your high beam headlights. Take your trucks lighting performance to the next level today!
Kit Includes: Jumper harness and T-taps.
Please use the wiring digram below to show you where this harness needs to attach to your LCM connectors under the driver dash.
