Thanks to everyone who helped me pull this off. After watching the videos this really wasn't a hard install. It just took a little patients. I ended up finding a set of steps, off an 2018 Denali, on facebook marketplace of all places. I started to put together a parts list of all the wire, wire terminals, connectors and tools. From there I decided it was easier, for me, to buy the chassis wiring harness and stripped out what I needed. It was really easy once you started and all the original mounting hardware is already mounted on the harness. It ended up looking like a stock install. Again, thanks everyone for all your help!
