30-Way Female Wire To Wire Housing Natural Automotive Connector – TS30378-30P-21-1 for Toyota 90980-12E91 Compatibility

The 30-Way Female Wire to Wire Housing Natural Automotive Connector, model TS30378-30P-21-1, is a high-reliability female receptacle engineered for seamless integration in automotive audio and control wiring systems. Designed to mate with the male connector TS30378-30P-11-1, this natural-colored 30-pin housing serves as a critical interface in vehicle-specific harness adapters, particularly for Toyota models using the OEM connector 90980-12E91. It enables installers to connect aftermarket head units to factory wiring without cutting or modifying original cables, preserving vehicle integrity and simplifying upgrades.

Widely used in car audio retrofitting, marine electronics, UTVs, and recreational vehicles, this female connector ensures stable transmission of audio signals, power lines, ground circuits, and accessory triggers. Its natural (beige/off-white) housing blends with factory harness aesthetics, reducing visual clutter and helping technicians identify correct mating pairs during installation. Built for durability and long-term reliability, the TS30378-30P-21-1 is a trusted component in both professional and DIY vehicle electronics projects.

Natural-Tone Female Housing for Factory-Style Integration

The TS30378-30P-21-1 female connector features a natural beige housing that matches the original equipment appearance in many Toyota vehicles, supporting clean, professional installations. As the receptacle side of a wire-to-wire connection, it securely accepts the male plug TS30378-30P-11-1, forming a tight, vibration-resistant junction that maintains signal continuity under real-world driving conditions. The internal cavity is precision-molded to guide Terminals into proper alignment, minimizing insertion force and preventing terminal damage during mating.

Constructed from either PBT+GF15% or PA66+GF30%, the housing delivers excellent resistance to heat, impact, and chemical exposure. These reinforced thermoplastics maintain structural integrity across extreme temperature ranges, making the connector suitable for use in dashboards, engine bays, and other demanding environments where long-term stability is essential.
