My 2002 4.4 alarm's will go off now twice a week for no reason.

I had a 7 Series that did the same thing, it was a common problem that the motion sensor in the headliner would go bad. It cost around $80 and two screws to change.

Has anyone here know the fix?

Or can anyone tell me where the alarm horn is s I can disconnect it.
