    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.

    You won’t have the remote start capability until all your trouble codes are cleared.

    Did an alternator test today.

    It’s only putting out 12.3v at idle, so it’s toast.

    Hopefully that fixes everything.
