automatic headlights

I have a 1998 firebird which has the automatic headlights on it. Does anyone know where the sensor is for this? I would really like to disable this feature because the lights often come up during the daytime if I park in the shade and i feel i would get a lot life out of my motors if i didnt have the automatic headlights. Since the car is in storage over the winter i can't easily go look to see if there is just a fuse i can pull, but any help would wonderful
