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....
