Hello Kevin.
The correct wiring kit to flat tow your 2024 GMC 2500 HD with LED lights is the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267. This diode kit is great because it ties into your vehicles wiring so you can use your blinkers and brake lights while flat towing, and the diodes prevent electrical feedback which could cause damage to your trucks electrical components. This kit also includes the 6 way connector for the front of the vehicle, as well as the cord to connect your coach to your 2500.
We do not have a plug-n-play wiring option for the 2024 GMC 2500 if that is what you were referring to.
