Retrofit 2022+ Digital Instrument Cluster in 2021 Yukon Denali

I do have one last question. Apologies up front lol. What does and doesn’t work until you get the dealership to do their thing.

I did it myself so I just had check engine and other lights on (I have a MDI2 and Delco account for my Tahoe). So you will probably just have a bunch of lights on, but the tech will plug in and they have to run a command which will reset all the lights then clear the DTC's and will then work perfectly fine after. Make sure you tell them DO NOT PROGRAM! That will mess it up. They will send you a sheet on what exactly you have them do and thats all they should do.

Sounds easy enough
