2019 and newer Chevrolet Silverado, GMC Sierra and International CV 4500, 5500 and 6500 trucks come with upfitter switches. But if you have several options equipped, you may be left with just 1 auxiliary switch. The cargo light switch is useful as an extra aux. switch. This also applies for anyone with 2014 and newer 1500, 2500 and 3500 trucks wanting to use the cargo light switch.
