Wierd wierd question

Well Ive been trying to identify a electrical box on my car for the past week now, finally figured it out. There is a Flex-a-lite fan control module next to the battery, all wired in, but guess what? NO FAN???? What the heck would you use a fan control module without an electric fan for? Any ideas on what I could re-utilize this box for? Ill throw a pic up in a bit when I get a chance and show you what I mean.
