Yes, that certainly is an option, if you want a horn honk. You are then using the relay contacts to operate the horn, instead of the voltage across the relay coil to make the tone buzzer sound. I suggest that you make a very good connection (solder or crimp), because the horn will require much more current (several amps instead of just milliamps). Just wrapping the wire for the horn, as I did for the low current buzzer might (probably will) create a high resistance connection resulting in heat at that connection. That was and is one of my concerns about operating the horn with the keyless entry relay. Making a connection to the wire running to the receptacle for #87 would be the best way to connect if you can find it under the fuse box. Working with the higher current devices requires very good electrical connections.
