Wiring Adapter - SoundBomb to BMW OEM Harness

DENALI BMW Horn Wiring Adapter — Plug In. Sound Off.

The DENALI BMW Horn Wiring Adapter makes installing a SoundBomb horn on your BMW clean, simple, and truly plug-and-play. No cutting. No tapping. No messing with the factory harness.

This adapter plugs directly into the OEM BMW horn connector, allowing your horn upgrade to work from the original factory horn button while keeping the motorcycle’s wiring untouched.

Built for Simple Installation

For the SoundBomb Mini, this adapter is all you need for a direct plug-and-play connection.

For the SoundBomb Original or SoundBomb Split Horn, this adapter is used with the DENALI SoundBomb Horn Wiring Harness. It sends the trigger signal from the factory BMW horn plug to the SoundBomb harness, so your upgraded horn functions exactly like stock — just a whole lot louder.
