Don't have my car here to look and see if I have one of those but I'm gonna guess it's either some kind thing for boosting your radio signal or possibly for a cb setup?

That or it's a tracking signal placed in your car by visiting aliens so they know how to find you when they return. Better watch out for the alien anal probes!!
