Where is the LCM on a Hummer EV?
The LCM (Light Control Module) on the EV vehicles can be in a different location than the regular Gas/Diesel vehicles. We have noticed in the Hummer EVs at least that these are not on the driver's side.
The LCM (Light Control Module) on the Hummer EVs are usually located on the Passenger Side area behind the Glove Box.
For example, on a 2024 Hummer EV you can find the LCM on the right side of the passenger area.
To best describe its location - it's on the far right side of under the glove box.
Here is an image showing the location area:


The installation process for this is the same as it would be for a Silverado, Sierra, Tahoe, etc.
The Violet plug is the second one in from the Light Blue plug.
Before installing it's always required to have the driver and/or passenger door open for 10 minutes minimum or you can disconnect the battery for installation.
