2021 Tahoe Illuminated door sills

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!

Thanks! Can you send me pictures of your Bcm under the dash.

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.
