28Pin 2mm 1.6mm Grey Wire Harness Connector with Terminals Automotive Connector for Select Toyota Car – OEM-Compatible Audio Interface for Factory Harness Integration

The TS30101-28P-21-2 is a 28-position female grey automotive connector specifically designed for use in aftermarket audio installations on select Toyota and compatible vehicle models. As the female receptacle that pairs with the male plug TS30101-28P-11-2, this connector enables a clean, plug-and-play installation method that preserves the original factory wiring. By eliminating the need for cutting or splicing, it allows for a reversible upgrade process, making it ideal for both professional installers and DIY enthusiasts who want to maintain vehicle integrity while enhancing audio performance. The grey housing is commonly found in OEM harness systems, ensuring visual and functional compatibility during integration.

This connector supports full signal transmission across all essential audio and control circuits, including left and right speaker outputs, power supply, ground, illumination, and steering wheel control inputs. Its precision-molded design ensures secure terminal retention and reliable mating, minimizing the risk of signal loss or intermittent connections caused by vibration or thermal expansion. Suitable for use in passenger cars, marine yachts, UTVs, and off-road vehicles, the TS30101-28P-21-2 delivers consistent performance in environments subject to moisture, dust, and mechanical stress.

Key Specifications

Grey Housing for OEM Matching and Easy Identification

The grey housing of the TS30101-28P-21-2 provides a professional, factory-matching appearance that blends seamlessly with original vehicle wiring looms. This color is commonly used in OEM harness systems for specific Toyota models, making it easier to identify and install without confusion. The neutral grey tone offers better visibility than black connectors in low-light conditions, aiding technicians during complex installations. It also resists fading and discoloration over time, maintaining a clean, like-new look even after years of service under the dashboard.

Durable Materials for Harsh Automotive Environments

Manufactured from high-performance thermoplastics—PBT+GF15% or PA66+GF30%—this connector is built to withstand extreme temperatures (-40°C to +120°C), mechanical shock, and exposure to oils and solvents. These reinforced materials ensure long-term dimensional stability and prevent housing deformation. The internal terminals are made from copper alloy, brass, or phosphor bronze, offering excellent electrical conductivity, low resistance, and strong resistance to oxidation. This robust construction ensures reliable signal transmission and long service life in demanding applications such as marine audio systems, off-road vehicles, and high-mileage passenger cars.
