The horn worked fine on a bench test. All the wires are securely attached.
There is no cracks or brakes in the plastic. The chrome is rough it is not dented or dinged but has tiny dots all across it.
The mount bracket is still attached to it and will be shipped with the horn.
This item is a ready to install item if looks are not an issue.
