OK, so you are using a 90s style control box with the "self test" horn. In other words, the horn chirps for a second every time you turn the key on, correct? Dan is soooo right about the plugs, use of the non inductor plugs can drive the warning systems crazy. You mention the engine isn’t overheating but the horn shuts up with the temp sender disconnected. Like Dan says, try to route the send leads as far away from the coils/plugs/wires as possible.
Replacing that sender is a royal pain on that engine. Do you have another control box you could just plug into the engine to try out? I suppose an intermittent/bad positive connection to the horn, or perhaps a weak horn ground might drive it crazy as well. I don’t know how voltage sensitive these horns are, but suppose real low or excessively high battery voltage might drive the horn crazy as well.
