Car alarm with a mind of its own

[suprascoot]

Hello all,

Ive got an 89T Automatic with an alarm that randomly goes off. I goes off when locking the car from the inside, outside, or locking the inside and holding the handle up while closing the door. I think one of these activates the alarm while the other does not but I don't know which is which. I am at the point, as are the people who have to sit and listen to my car alarm, where i just want to rip the dam thing out.
My question comes here...has anybody successfully done this. Being the alarm system is connected to so many other electrical systems throughout the car, I have the haunting suspicion that it wont simply be unplugging a little computer.
Anyways any help will be greatly appreciated
