After doing some research and trying to figure which wire to tap into on my 19 Sierra to add footwell lighting this is what I came up with. These are not the same as my 18 silverado was at all. To get the added led lights I purchased to come on and fade in and out with the overhead lights I had to tap into the BCM connector #1 pin 23 which is a grey wire. The lights look awesome and you can see now.
