JOYN Speaker Signal Harness with Full Power and Ground Connectors (for Toyota JBL, Lexus, and Crown, 30-Pin) JL30

This wiring harness is designed for those considering expanding their car audio setup by adding speakers, subwoofers, or an external amplifier. By inserting it between the vehicle's factory coupler and the amplifier/audio unit, it allows for safe and reliable signal extraction and branching without cutting the factory wiring. Even those unfamiliar with electrical systems can easily install it. All wiring is pre-distributed and equipped with bullet terminals. No tools or crimping is required; it can be directly connected to commercially available equipment or existing audio components. It is especially user-friendly for DIY audio customizations and those looking to work efficiently within a limited time frame. The wiring uses high-quality OFC (oxygen-free copper) cable to minimize transmission loss in audio signals and power supply. This allows for signal extraction to external devices while maintaining the sound quality of the factory audio. The distributed wiring is also designed for easy identification and management, facilitating smooth installation. This product is compatible with select Toyota and Lexus vehicles equipped with the factory JBL sound system, Lexus sound system, or Mark Levinson sound system. Typical compatible vehicles include: Alphard/Vellfire (30 series, 40 series), Harrier (60 series, 80 series), GR Yaris, Camry (70 series), Land Cruiser (Reiwa era models and later), and all Lexus vehicles (premium sound/Mark Levinson equipped). This product's coupler is compatible with the following OEM part numbers: 90980-12979 / 90980-12964. It can be used with a wide range of vehicles using these couplers. Note: This product comes with pre-processed terminals, so no additional processing is required. However, this product is intended for users with wiring knowledge. We cannot answer questions regarding specific connection methods or installation procedures. Please be aware of this before purchasing. Extend your factory wiring without any modifications! Simply insert it between the original couplers of your Toyota or Lexus vehicle to add an external amplifier or speaker.
