2021 Yukon RH tail light replacement

[Nautilus571]

So... my wife backed into my son-in-law's pickup busting the lens on the right tail lamp. Found one online at a junk yard in Wisconsin. When talkimg to the salesman at the yard he mentioned I may need to have the truck flashed at the dealer. So, two things:
1. is there a sticky/video explaining the replacement procedure
2. Do I need to have the system flashed after replacement of the assembly

Wow, that would be a first, but wouldn't surprise me. I don't know the answe to that one, but do share when you find out.

I replaced my RH tail recently no need for a flash total nonsense.
