keyless entry horn beep

Does anyone know how to disable the horn beep when using your remote keyless entry on a 98 trooper? I don't want to disconnect the horn all together because I might need to honk at an idiot someday, just want to disable the short honk when locking and unlocking my doors. Is there a wire that can be clipped that leads from the keyless unit to the horn? and if so does anyone know where it is?

Thanks
