This forum thread is incredibly useful. We have a 2013 model. I pulled the VSP module, opened it up, soldered a wire onto the back side of Pin 5, ran the wire out of a hole in the corner of the case as I reassembled the case, reinstalled in in the car, and touched the wire to ground. It worked! I do have one new bit of information. On the 2013 model the warning light is not in the instrument cluster as reported above (for 2012?) but is now next to the "passenger airbag off" warning light in the center console above the 12V power out.
