Ah I’m assuming you installed this yourself. As I’m fairly new to all things cars (this is my first purchased vehicle) I left it to a local shop to install.I have installed the Lasfit switches in my truck. They look just as OEM as OEM and are not tied into the BCM.
You only have to have the ignition switch set to ACC in order for the switches to function. The truck does not have to be running. The switches are getting their power from the 12v accessory plug.
If someone needed to have them working with the ignition completely off, they would just need to run an always on 12v source to the switches. The actual relays in the control box are connected directly to the battery.
