This Genuine Toyota Part is available as an option for your FJ Cruiser. If your FJ Cruiser only has the standard single horn (mounted behind the grill), this will transform the wimpy sound of your stock FJ horn into a horn that commands attention. With this kit, you can tap into the factory horn wire with supplied tap, and simply bolt the new horn with the old. The results are dramatic! See photos below for the install on our Project FJ Cruiser.

Simply tap into the factory horn wire.

Then bolt the second horn along with the factory horn using the factory hardware.
