That is exactly what I am thinking, I did locate a plug adjacent to the hood latch with a spring loaded cover, but the pin/plug configuration did not seem to match.
Actually I was pinned close to the garage wall and did not have a great look at this. With the snow drifted against the garage door I did not reposition the car.

Thanks,
Gary
