Welcome to ZDriver!!!

I would check the horn buttons on the steering wheel.

On like constantly blaring or kind of honking like an alarm horn?

If its going nonstop pull the relay for the horn and check it.

If its like an alarm is cuz it is. the Z32 had a factory alarm system. But thats I can offer in the way of help as I dont know much about it

I had the same problem in my camaro the horn relay had gotten stuck after i washed the engine bay

Water got in thru a crack of the relay

If its the harm alarm going off, with the battery connected and the horn going off walk over and unlock the drivers side door from the outside with the key. This should turn the alarm off.
