This will get the center high mount stop lamp (CHMSL) cargo lights on your Silverado or Sierra to work as both a cargo light and a reverse lamp. This will also enable your rear-facing tailgate cargo light (if equipped) to come on in reverse. The truck's cargo lights will also illuminate when you unlock the truck with the key fob at night as a courtesy lamp. The installation is very easy and takes less than 5 minutes while following our installation video.

Important Note: This harness will not activate your tow mirror cargo lights in reverse. If you'd like your tow mirror cargo lights to come on in reverse, you will need to purchase a supplemental cargo and reverse harness HERE.

    Easy Install & Worth Upgrade

    Cheap and easy upgrade. Very easy to install. Best feature is the bed lights turning on with the unlock button on the remote.
