28Pin Female Black Car Aftermarket Stereo Audio Connector 1-2188225-2 – High-Reliability OEM-Compatible Harness Adapter for Vehicle audio systems

The TS30243-28P-21-1 is a 28-position female black Automotive Connector engineered to provide a reliable, non-destructive method for connecting aftermarket stereos to factory-installed wiring harnesses. Designed to mate with the male plug TS30243-28P-11-1, this connector enables a plug-and-play installation process, eliminating the need to cut or splice original vehicle wires. The black housing offers a clean, OEM-matching appearance, making it ideal for applications where a discreet, professional-grade connection is required. This model is commonly used in audio interface kits for Toyota, Lexus, and other Asian-market vehicles that utilize a standardized 28-pin black connector for audio and control signal transmission.

Perfect for both DIY enthusiasts and professional installers, the TS30243-28P-21-1 supports full signal integrity across all essential circuits, including speaker outputs, power, ground, illumination, and steering wheel control inputs. Its secure locking mechanism ensures a stable, vibration-resistant connection, making it suitable for use in passenger cars, marine yachts, UTVs, and off-road vehicles where durability is critical. By preserving the original factory harness, this adapter allows for easy removal or future upgrades, offering a clean, reversible solution that maintains vehicle integrity while enhancing audio performance.

Technical Specifications

Black Housing for Seamless Factory Integration

The black housing of the TS30243-28P-21-1 provides a low-profile, OEM-matching appearance that blends naturally with factory wiring harnesses. Unlike colored connectors, black is often used in standard vehicle platforms where a universal, non-descriptive connector is required. This makes it ideal for applications where visual consistency with original equipment is essential, such as in dealer-level installations or high-end audio upgrades. The neutral color also helps reduce confusion during complex wiring jobs, allowing technicians to focus on correct pin alignment and secure connections without distraction.

Engineered for Durability in Demanding Environments

Manufactured using high-strength thermoplastics—PBT+GF15% or PA66+GF30%—this connector delivers excellent resistance to heat, impact, and chemical exposure. These materials are designed to withstand extreme temperature fluctuations (-40°C to +120°C) without deforming or cracking, ensuring long-term reliability. The internal Terminals are made from copper alloy, brass, or phosphor bronze, providing superior electrical conductivity, low contact resistance, and resistance to corrosion. This construction makes the connector suitable for use in harsh environments such as marine yachts, off-road vehicles, and commercial fleets where vibration, moisture, and thermal stress are common.
