28Pin Female White Car Aftermarket Stereo Audio Connector 2188225-1 – Factory-Style Harness Adapter for Vehicle Audio Upgrades

The TS30243-28P-21 is a 28-pin female white Automotive Connector designed to simplify the integration of aftermarket stereos in a wide range of vehicles. As the female receptacle that pairs with the male plug TS30243-28P-11, this connector enables a plug-and-play solution for replacing factory-installed head units. The white housing offers a clean, neutral appearance that blends well with most factory wiring harnesses, making it ideal for discreet installations where visual consistency is important. This model is commonly used in audio adapter kits for Toyota, Lexus, and other Japanese automotive brands that utilize a standardized 28-pin white interface.

Engineered for reliability and ease of use, the TS30243-28P-21 supports full signal transfer including audio channels, power delivery, ground connections, and auxiliary controls such as steering wheel audio buttons and dashboard illumination. It eliminates the need for cutting or soldering original vehicle wiring, preserving the factory harness and allowing for easy restoration or future upgrades. This makes it a preferred choice for professional installers, car audio shops, and DIY enthusiasts looking for a clean, reversible, and secure connection method.

Technical Specifications

White Housing for Clean, OEM-Like Installations

The white housing of the TS30243-28P-21 is specifically designed to match the color of factory wiring harnesses in many vehicles, ensuring a clean and professional appearance under the dashboard. Unlike colored connectors that stand out, this white version integrates seamlessly with original equipment, making it ideal for installations where a low-profile, factory-original look is desired. It is often used in premium audio upgrade kits where aesthetics and reliability are equally important. The housing includes alignment guides and locking tabs to ensure correct mating and prevent accidental disconnection due to vibration or movement.

High-Performance Materials for Long-Term Reliability

This connector is built using durable engineering plastics—either PBT+GF15% or PA66+GF30%—which provide excellent mechanical strength, heat resistance, and dimensional stability. These materials are resistant to warping, cracking, and chemical degradation, ensuring long-term performance in automotive environments. The internal Terminals are crafted from copper alloy, brass, or phosphor bronze, offering superior electrical conductivity and resistance to oxidation. This combination ensures minimal signal loss and consistent performance across audio, power, and control circuits in cars, yachts, UTVs, and other specialty vehicles.
