2020+ PIU Dimmer Wire

I read through the upfitter's manual and it doesn't really give any details. For the 2020+ PIU there's a "Dimmer" wire in the center console. Is that just 12V+ when the headlights are on? Or is it variable based on the dimming level? I was debating using that as a trigger for dimming the lightbar when the vehicle is in park (since I don't have the sensor on the bar).

If it's the same as the 2016+, the dimmer wire is for panel illumination with the lights on that dims with the rest of the panel lights. Supposed to be used for panel illumination on added gear....

Yea, its an analog output. Voltage changes with the brightness of the gauges.
