## Description

ラウドネス:150db±5db パッケージリスト: エアホーン x 1。 リレー x 1。 ハーネスパッケージ x 1。 フィルター x 1。 ネジ、ナット、クッションブロック1個。 3Mライン付きボタン1個。 いくつかの一般的な配線エラー: 1. 接続後、ホーンボタンを押してください。ホーンが鳴らない場合、リレーがガタガチャ鳴らない場合は、青い線と白い線が誤って接続されていることを意味します。 それぞれ元の車の電源に接続する必要があります。 純正車のホーンラインやバッテリーを接続できます。 2. エアポンプは泣き声を出しますが、ホーンは鳴りません。つまり、エアポンプの下のプラス端子とマイナス端子が逆に接続されています。 黄色のワイヤーをプラス極に、黒いワイヤーをマイナス極に差し込みます。 3. ホーンの音が安定せず、時には壊れることがあります。 これは、黒いワイヤーが接地されているフレームにペイントがあり、負極の通常の電源オンに影響するためです。 良好な電源オン位置に接続されている限り、問題ありません。

### ⭐⭐⭐⭐⭐ Review
*by S***E on April 15, 2024*

This is my 2nd vehicle which I add this type of horn. First was a Bad Boy and now this one, the Farbin. This is a fraction of the price of the Bad Boy, AND, it comes with all the wiring and relay, so much better deal. They both sound pretty similar, so really no justification to pay more. Installation took a while given the tight spaces and the difficulty to thread the button wire from the inside to the engine bay. Nothing related to the horn itself. But I did find the manual lacking in details and photos. Had to research and analyze it for a while (I'm not a pro installer nor an electrical engineer). So there's definitely room for improvement in the installation instructions space.
