2000 Cougar wiring diagram?

Does anybody know where i can get the Wiring diagram for a 2000 Mercury Cougar. My sister has an alarm and she wants it installed, and i figured i would help her out to put it in. Now i know how to do all that stuff, but i don't know what wires are what exactly and don't want to take the risk of cutting or crimping something i don't know what it is. So if you guys could help me out on that, it would be much apprectiated, or at least put me in the right direction to do it correctly.
