I installed the kit last summer when I bought my 2021 Suburban. It was easy and it looks awesome.

I am having issues getting them to light up. 2021 premier suburban. Suggestions on bcm connections? Or do I need to go to dealer to have them unlock the feature.

Although I had mine installed at the dealer, a number of people on here have self-installed and did not need to have anything performed at the dealer, as far as I know.

These are some of the best upgrades I have done to my 2024 Tahoe. Illuminated door sills, illuminated front bowtie and keyless entry. All dealer installed and the price was reasonable and worth it!

Note: If vehicle was built before 8/3/2020, the BCM will need to be reprogrammed to enable sill plate light function. Refer to K9 Body Control Module: Programming and Setup in Vehicle Service Manual.
This is from the installation instructions. I installed my own on my 2021 Suburban and they work perfectly.
