Thanks Robert. But I'm ahead of you. I disconnected the horn yesterday. My car is parked closer to the neighbors' bedrooms than my bedroom, so it's high priority I don't disturb my neighbors.

George, the alarm is easier to disconnect on your model. Like M.B.Doc said, the starter interlock relay must be jumpered if the alarm is disconnected on my model. I'll have to get the schematics out and find which wire needs to be jumpered.

The ATA diagnostic faults on other models actually point to which switch (or circuit) activated the alarm. On my model I have to guess.
