Car Alarm Question

well, i got the bad boy in, and it works fine. but i can't figure out how to get the brake lights to flash when the alarm goes off. I got the headlights to, but can't get the brakes too. heres what i've tried so far. When i refer to "The Wire" i'm talking about the wire from the car alarm that i'm supposed to hook up to the brake lights.

-Hooking up the wire to the Brake Light Fuse inside the car
-Hooking up the wire to the Brake Light Fuse in the engine bay of the car
-Hooking up the wire to the actually wire that goes to the Brake Lights.

my last thought is to hook up to one of these 2 little wires that goes right to the brake pedel. i forget the name =/

i'm not sure if i'll get any help since i've never seen anyone use this section of the fourm, but any help will be greatfull appreciated (i know i spelt that wrong)
