This will get the rear-facing cargo lights on your Silverado, Sierra, Colorado, or Canyon tow mirrors to work as both a cargo light and a reverse lamp. They 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: The lights must be properly operating as cargo only prior to installing this harness. If your lights aren't operating at all, then please contact us to assist in getting them working properly first.

FAQ

How long does this take to install?

This is very easy to install and takes less than 10 minutes to install.

Will the cargo lights come on when I unlock the truck with my key fob?

Yes, as long as it is dark outside. The cargo lights will only illuminate if the ambient light sensor senses that it's dark outside.

Can I activate the cargo lights in drive, or only reverse?

This modification only activates them in reverse.

If you would like to have them activated in drive as well first add this to your cart, then add our cargo in drive harness to your cart by CLICKING HERE. These harnesses can be used in tandem - just stagger the taps on any shared wires.
