power door locks

My 2000 cavalier does not have any power door locks. I am thinking about converting them to power locks and was wondering if anybody knew anything about the wiring. I have also recently added an alarm to my car, and was wondering if it is difficult to hook the power locks to the keyless entry that comes with the alarm. Is it really hard to do? I need help with the wiring and finding out where the wires are located in the car. Please help.

A haynes manual will have a power windows wire harness in it, and the manual that came with the alarm (if it came with one) should show you how to hook up the keyless entry.
