Venoms Auto Fog Light Harness is designed to fit a wide variety of GM trucks. This harness allows your factory fog lights to automatically activate as soon as your headlights activate, even while your high beams are on.
From the factory, GM disables 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. If you want to wire them up so the fog lights activate when the engine starts, we will show you how to do that as well in the install video below. 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!
NOTE: This harness is compatible with our Amber DRL switchback kit and does not need changed from the install video shown below. If you have our Full Time Amber Kit for 2022-2026 full size trucks that keeps your DRL’s amber at night, please use this wiring dirgram:

Great product and simple install
Connectors could work better. Took a lot to make connection. When finally connected, look great and fog lights automatically come on when headlights do and stay on with brights.
Finally no more pushing the button to turn on the fog lights!!!! You can hook them up 2 ways 1 when you turn the truck on they will come on with the driving lights or when the head lights come on!! pick what ever is best for you!! easy to install. and with the video you can’t mess this up. Thanks Venom. you guys nailed it again. keep us updated with all the new add on you come out with as it sure makes our trucks fit our needs!!!
Super easy install. Kit works like it should. Great install video.
Works like a charm and even keeps the auto high beam feature intact. Fogs with the high beams are an added bonus. Install was simple and only took 5 minutes. Highly recommend!
