I intended to use this for an RC Odyssey, but I bought a different car, so I'm selling it. Unopened. This is for a horn, and includes the genuine conversion code ②. *If you don't need the genuine conversion code, I will discount it by 800 yen, so please comment. Please search for the sound, etc. This is a used item, so please purchase only if you understand. No returns, no refunds, no exchanges (3N).
