28Pin Female Green Car Aftermarket Stereo Audio Connector 7-2188225-7 – Durable OEM-Compatible Harness Adapter for Vehicle audio systems

The TS30243-28P-21-7 is a 28-pin female green Automotive Connector designed to provide a seamless, non-destructive method for connecting aftermarket stereos to factory-installed wiring harnesses. As the female receptacle that mates with the male plug TS30243-28P-11-7, this connector enables a plug-and-play installation process, eliminating the need to cut or splice original vehicle wires. The green housing serves as a color-coded identifier, helping technicians and installers quickly locate the correct interface during audio upgrades. This model is commonly used in Toyota, Lexus, and other Asian vehicle platforms that utilize a standardized 28-pin green connector for audio and control signal transmission.

Engineered for reliability and ease of use, the TS30243-28P-21-7 supports full signal continuity including audio outputs, power lines, ground connections, and auxiliary inputs such as steering wheel controls and dashboard lighting signals. Its secure locking mechanism ensures a vibration-resistant connection, making it ideal for use in passenger vehicles, marine yachts, UTVs, and off-road applications where durability is essential. By preserving the factory harness, this connector allows for easy restoration or future upgrades, offering a clean, reversible, and professional-grade solution for modernizing vehicle audio systems.

Technical Data

Green Housing for Easy Identification and OEM Matching

The green housing of the TS30243-28P-21-7 provides a distinct visual cue that simplifies the installation process, especially in vehicles with multiple connectors under the dashboard. This color-coding helps prevent misconnections and speeds up the upgrade process, making it ideal for both professional installers and DIY users. The green variant is often used in specific vehicle models or trim levels where manufacturers assign different colors to various control or audio circuits. This ensures compatibility with factory systems that require a green-coded female interface for proper signal routing and system recognition.

High-Performance Materials for Long-Term Reliability

Constructed from reinforced engineering thermoplastics—PBT+GF15% or PA66+GF30%—this connector delivers excellent mechanical strength, thermal stability, and resistance to environmental stress. These materials are engineered to withstand extreme temperatures, vibration, and exposure to automotive fluids without degrading. The internal Terminals are made from copper alloy, brass, or phosphor bronze, offering superior electrical conductivity, low contact resistance, and resistance to oxidation. This combination ensures consistent signal transmission and long-term durability in demanding applications such as marine environments, off-road vehicles, and high-performance automotive systems.
