Alpine HRN-TSLA-M3B3 Plug-and-Play Harness for Tesla Model 3
Alpine HRN-TSLA-M3B3 is a plug-and-play harness designed for the Tesla Model 3 with Factory Base Audio. It is made specifically for use with Alpine’s Complete Tesla Audio Kit, helping integrate the upgraded sound system while retaining the efficiency and factory features of the vehicle.
Why deal with a complicated audio connection when a purpose-built harness can make the integration more straightforward? The HRN-TSLA-M3B3 comes pre-configured for the applicable Tesla audio setup, giving you a clean connection between the factory system and Alpine’s audio components.
Designed for Alpine’s 13-Speaker Sound System
The HRN-TSLA-M3B3 is designed for full audio integration with Alpine’s 13-Speaker Complete Sound System Upgrade Kit for Tesla Model 3 with Factory Base Audio. It is specifically intended for use with the Alpine PSS-TSLA-M3P.
The harness helps connect the components needed for the upgraded audio system while allowing the Tesla’s factory features and controls to remain part of the experience.
Plug-and-Play Audio Integration
With its pre-configured design, the Alpine HRN-TSLA-M3B3 is built around seamless integration into the Tesla Model 3. Think of it as the connection point that brings the Alpine audio system and the vehicle’s existing setup together without changing the basic way you interact with your Tesla.
The harness includes one integration harness and one 12V amplifier power harness with an Alpine fuse holder, providing the connections required for the compatible Alpine audio system.
Supports Intel and AMD MCU
The HRN-TSLA-M3B3 supports both Intel and AMD MCU configurations. This is important because Tesla Model 3 vehicles can have different configurations, making fitment confirmation an essential step before selecting the harness.
Use the Alpine VIN Decoder for Fitment
Alpine created its Tesla VIN Decoder to help determine the correct harness for your vehicle. Simply enter the Tesla VIN and build date in MM/YYYY format to receive fitment results in real time.
This means you do not have to rely on guesswork when determining whether the HRN-TSLA-M3B3 is the right model for your Tesla. The harness requires compatible vehicle fitment, so checking the VIN and build date before purchase is essential.
What’s Included
- 1 integration harness
- 1 12V amplifier power harness with Alpine fuse holder
Made for a Specific Alpine System
The Alpine HRN-TSLA-M3B3 is not a universal Tesla audio harness. It is designed specifically for the Alpine PSS-TSLA-M3P and for Tesla Model 3 vehicles equipped with Factory Base Audio.
That focused design makes the harness part of a complete audio integration solution rather than a standalone upgrade component. When paired with the compatible Alpine system, it is intended to help deliver the upgraded sound performance while maintaining the vehicle’s existing features and controls.
Check Your Tesla Before Ordering
Fitment is the key consideration with the HRN-TSLA-M3B3. Before ordering, enter your VIN and build date to confirm that the harness matches your Tesla Model 3 configuration. The Alpine VIN Decoder was created specifically to simplify this process and provide a real-time fitment result.
For the right vehicle and compatible Alpine system, the harness provides a direct path toward integrating Alpine’s complete audio upgrade into the Tesla Model 3 with Factory Base Audio.
Bring Alpine Audio Integration to Your Model 3
The Alpine HRN-TSLA-M3B3 combines a vehicle-specific design with plug-and-play audio integration for select Tesla Model 3 vehicles. With support for Intel and AMD MCU configurations, a dedicated integration harness, and a 12V amplifier power harness with Alpine fuse holder, it is built to work as part of Alpine’s complete Tesla audio solution. Confirm your VIN and build date first, pair it with the compatible Alpine PSS-TSLA-M3P system, and the harness provides the connection needed for Alpine’s 13-speaker audio upgrade.
