Mystery car part

After getting a flat tire I decided to take care of a few (read very few of the car maintenance tasks I know how to do. In the course of doing this I happened to pop the hood and discovered a part simply sitting on the little ledge at the very front. It looks like it takes two tubes and has a two prong socket for some sort of electrical connection. I believe at least a few of people reading these posts do more car maintenance than I do. Anyone recognize this part?



Sorry for the poor quality, the pictures were taken in poor lighting with a sub-mega-pixel cell phone camera. The writing on the side is, "210 4047-2 Delco Remy." I was able to find the web site for Delco Remy, but their online part number lookup system doesn't appear to know about this thing.

This doesn't seem to have come from my car since I couldn't spot any loose tubes or electrical cables. If it was an old part that was replaced then it would have been sitting there for over a month. And if it had been on the road it seems really unlikely for it to successfully be kicked up into that spot.
