silverado777 Posted July 24, 2008 Report Share Posted July 24, 2008 On my dash i have a dome thing that looks about the size of a marble. Does anyone know what it is or what it does? It's about in the center of the dash where the windshiel and the dash meet. Quote Link to comment Share on other sites More sharing options...

silverado777 Posted July 24, 2008 Author Report Share Posted July 24, 2008 I see thanks guys.I was going to turn it into a flashing light for mr alarm since some disrespectful jackass tried to break into my truck a couple of days ago. They didn't get it thankfully but they did cause a bit of damage. Quote Link to comment Share on other sites More sharing options...
