Dual Function (Third Brake Light Bed Cargo & Reverse) Wiring Harness - 2019-2024 Silverado & Sierra
Enter Vehicle To Check Fit
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.

Such an easy install. Took maybe 5 minutes. T-taps make it super simple. Support is amazing if you have any questions or concerns. One of the best customer service I’ve ever experienced!
End results are great
I did somehow manage to click on the incorrect installation video and hooked into the wrong connector at first. Quickly remedied by finding the right video. Definitely easier than my last truck with the diodes. Thanks guys!
Just as expected
