I will try and explain this as best I can. I have a 2003 sel. on the center of the dash close to the windshield there is a little module that sticks up. If you look real hard you can see that it is a light. In fact on the Ford trucks and SUV it lights up when you arm the alarm. On the Taurus the alarm light is on the instrument cluster. So why is it there and can you use to as the alarm light?
