<added correct crossposting>

I normally scold people for multiposting, but I'm just getting over a
bad bout of flu and am too tired for that.

I quote below what I said in reply to your identical message in the
other group:

"This particular vehicle has no horn relay (no kidding).

"The horns in the 2nd gen Integra are always hot, with ground being
normally supplied by closing the horn switch in the steering wheel hub.

"The horns are located behind the outside ends of the front bumper,
meaning they can get good and wet and salty, especially if the splash
shields are torn or missing.

"If your horns are going off by themselves, chances are pretty good the
electrical connector at one of the horns is shorting out due to
corrosion."

I should also add that if the horns happen to dry out enough, they may stop
shorting long enough to resume proper operation until they get wet again.
