Attached to the brake pedal itself... if the pedal goes up towards the dash, you'll see it at the top of the pedal by the linkage... it's a simple contact switch. If the pedal goes into the floorboard, you'll have to open the hood and see where it goes through the floor... again, just a simple contact switch.
It means the ABS (Antilock Brake System) has a problem and is not in working order. Until the problem is fixed the light will remain on.
