Thank you to everyone who have contributed in this thread! All of the info really helped with the project. I'd like to mention my successful install.
2015 Silverado Z71 LT. I have power foot pedals. I was lucky and had the female connector port already under the console and it was hot. Everything was plug and play for me. Heated steering wheel, lights and all functions work!
Part numbers:
clock spring: 23381964
steering wheel: 84222909
I had some trouble fishing the clock spring wires out, so please be patient. It also made it easier that I have snap ring pliers as well.
Since your battery is disconnected, please note that you will need to put some muscle in when cranking the steering wheel to each side. I just took my e-brake off and allowed the truck to roll a little (I was parked on a slope) when turning the wheels.
Overall, the job was a lot harder than I anticipated but still only look about 1.5 hours.
