Question:
Battery disconnect switch. I have a 2024 gmc 1500 Denali 4x4 3.0l diesel. Do you have a current video on how to install the Air Force 1 air brake system on the truck I mentioned and which battery disconnect do I use. I removed my Air Force 1 from my f150 and will install it on my new truck. Thank you for your help.

Hey Michael congrats on the new truck! The most recent video I have of the Air Force One Flat Tow Brake System item # SM99243 being installed is on a 2020 Sierra 1500. I have linked this video below. Your 2024 is the same generation so it should be a similar installation process.
The correct battery disconnect for your diesel 1500 Denali is the Roadmaster item # RM93MR.

Hey Michael, how did the Air Force One install go on your new Denali? Did the Roadmaster battery disconnect fit and function the way you expected? Your update could make it easier for others setting up the same system.
