Horn intermittently turns on?

Greetings,

I have the car listed above without the air bag and without the radio buttons on the steering wheel. When I turned the steering wheel while maneuvering in the parking lot the other week my horn intermittently came on and it happened so much that I disconnected the two horns inside the front left fender. I believe the problem lies inside and behind the steering wheel and column. Therefore, if this is the case. I would like to have the schematic for the horn, exploded views and diagrams, and procedures to remove the steering wheel and replace whatever parts are necessary. I could not determine which fuse was the proper one for the horn either. I could not see it. I only saw CTSY and, Cig and those did not disable the horn when it was coming on unwantedly.
Thanks
