28Pin Male Blue Car Aftermarket Stereo Audio Connector – Reliable Plug-and-Play Harness Component for Toyota & Japanese Vehicles

The TS30243-28P-11-4 is a 28-pin male blue Automotive Connector designed specifically for seamless integration with factory audio systems in select Toyota and other Japanese vehicle models. As the male half of a matched connector pair, it mates directly with the female housing TS30243-28P-21-4, enabling a secure, solder-free connection for aftermarket stereo installations. The bright blue housing provides a clear visual distinction from factory wiring, making it easy to identify during installation and reducing the risk of incorrect connections. This connector is a vital part of modern car audio upgrade kits, allowing for clean, reversible installations that preserve the original harness and support warranty-friendly modifications.

Ideal for both professional installers and DIY enthusiasts, the TS30243-28P-11-4 simplifies the process of replacing factory head units with aftermarket receivers. It supports reliable transmission of audio signals, power, ground, and accessory control lines, ensuring consistent performance across various vehicle systems. Commonly used in applications for Toyota Camry, Corolla, Avalon, and other models, this connector delivers a precise fit and long-term durability in demanding automotive environments.

Product Overview

Benefits of a Blue Automotive Harness Connector

The blue housing of the TS30243-28P-11-4 offers superior visibility under the dashboard, making it easy to locate and connect during stereo upgrades. This color-coding helps prevent installation errors, especially in vehicles with multiple connectors of similar size. Blue is a popular choice for aftermarket kits because it clearly differentiates the upgrade component from factory wiring, which is typically black, grey, or white. This visual clarity improves serviceability and reduces labor time, making it ideal for both retail installers and high-volume shops.

High-Grade Materials for Long-Term Reliability

Manufactured from PBT+GF15% or PA66+GF30%, the connector housing delivers excellent mechanical strength, heat resistance, and dimensional stability. These reinforced thermoplastics withstand harsh automotive conditions, including extreme temperatures, vibration, and exposure to oils or cleaning agents. The internal Terminals are made from copper alloy, brass, or phosphor bronze—metals known for their high conductivity, spring properties, and resistance to oxidation. Together, these materials ensure a stable, low-resistance connection that supports clear audio and reliable power delivery over time.
