Fuse a 12 volt relay to the battery with a switch in line with the coil, use 
a normally open contact to interrupt the hot wire to the starter relay and 
intercept the run ignition wire through a normally closed set of contacts and 
on to the horn (regular car horn or an installed extra in the cockpit).
Now if the key is turned to start or the ignition is HotWired  without first 
energizing the relay the horn will sound.
