The horns are placed on the two small brackets which are fixated on the radiator crossmember. To remove the electrical connector found on the horn, unlock the release tab and then remove the connector away. Next, unscrew the horn mounting bracket bolt and then, take off the horn and the bracket. Remove the bolts and screws that connects the bracket to the old horn and tighten them to the new horn. The process of installation is the opposite of the removal process delivered in Flight.
