Hello all,
Does anyone know whether there is a signal coming out of the BCM or elsewhere on the 2016 vintage truck that indicates when the factory alarm (no interior motion sensor) system is armed? I want to add a sensor that will beep when something in particular occurs on the truck. However, I don't want the sensor to beep unless the alarm is armed. I have the 13000+ page (I'm not kidding) factory service manual, however I haven't been able to find a signal in the wiring diagram that will tell me when the alarm is armed.

Thanks
