While messing with the flasher relay, I noticed the black box located under said relay. the box appears to be an add-on and seems to be connected to the relay indicated (which also looks like an add-on).

I was wondering if it may have something to do with the engine cooling fan retrofit? I'm sure someone here will know!
Mine is a 2012 car by the way.
