It’s on the passenger battery box.

Whenever I unplug it the voltage shoots up.
Not sure what the relay pictured is for, but I doubt it has anything to do with the grid heater.

I don’t have access to the electrical diagram for your 2010 model.

Hopefully someone else who does will chime in.

Meanwhile I would pull one fuse at a time to see which one powers it to get more information.
