Venom’s Auto Fog Lights Harness will allow you to activate your fog lights automatically, even with your high beams! There are 2 different ways to install and it’s user preference. Either automatically as soon as the engine starts or when your low beam headlights turn on. We show both methods in the installation video. From the factory the fog lights will not turn on with your high beams activated, this harness will correct this!

Our Auto Foglights Harness will allow you to always have your fog lights on anytime the engine is running, regardless of light settings you have selected from inside the cab. As soon as you start your engine, 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 only activate when the headlights turn on using the parking lights, 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!Â

They will help you with any thing you need for your custom ride. I will shop with these guys again. Great service, pricing, and great products!
Fairly easy install. Would like a third connector so you could switch from always on to partly on.
Fogs work great on low/high beams and the auto high beam actually works with the fog lights activated.
No more having to turn the fog lights on manually at each key turn.

Fast shipping. Easy install. Love that the fogs come on automatically now and stay on with the high beams.
Very quick install, the video walks right right thru it. Great Product. Highly recommend.
