Thanked 331 Times in 233 Posts bout a relay, a switch and some wiring for being cheap...

tap into the interior lighting somewhere, run a wire out to somewhere on the exterior you could hide a switch to enable/disable, edge of the hood or under the front bumper or something. then from that switch to a relay, from the relay to the existing car horn.

interior lights come on = car horn
