Is there a fuse related to just the alarm that I could just pull?
Are you sure this is the alarm, or is it just the horn?
I have the same problem in my 97 Legend, where the Horn will sound when the headlights is on.
It is not the alarm, because there is a patter for the alarm to sound, but the horn will just sound forever.
If so, you will need the Multiplex Control Unit.
