DESCRIPTION
The Venom Trucks Auto Fog Lights Harness is a simple lighting control upgrade designed specifically for the 2021–2024 GMC Yukon. From the factory, GM disables the fog lights when the high beams are activated. This harness bypasses that limitation, allowing the fog lights to stay on with the headlights and remain active even when the high beams are turned on.
Once installed, the fog lights automatically activate whenever the headlights turn on, regardless of the light setting selected inside the cab. That means no more manually pressing the fog light button every time you drive at night.
This is a clean, practical upgrade for Yukon owners who want better lighting performance, improved visibility, and more convenient fog light operation without replacing the factory lights. The kit includes the jumper harness and T-taps needed for installation at the LCM connectors under the driver-side dash.
