6Pin 2.54mm Male Black Car Aftermarket Stereo Audio Connector – TS30362-06P-21 (Replaces 31073-1040) – Durable Automotive Harness Solution

In the fast-evolving world of car audio upgrades, compatibility and reliability are non-negotiable. The TS30362-06P-21 is a precision-engineered 4-pin male connector designed to serve as a direct replacement for the 31073-1040 model, commonly found in aftermarket stereo systems and OEM harness configurations. With its compact black housing and high-grade internal components, this connector ensures stable signal transfer for audio and control functions across a wide range of vehicles—including cars, UTVs, yachts, and recreational equipment—where dependable electrical connections are essential.

Precision 4-Pin Male Connector for Reliable Aftermarket Audio Integration

The TS30362-06P-21 is built to meet the exacting demands of modern vehicle audio installations. Its 2.54mm pin pitch ensures compatibility with standard circuit layouts, while the male configuration allows seamless integration into factory or custom harnesses. Designed as a plug-and-play solution for the 31073-1040 connector, it eliminates the need for manual wire splicing, reducing installation time and minimizing the risk of connection errors during stereo upgrades.

Durable Thermoplastic Housing for Long-Term Stability

Manufactured from either PBT+GF15% or PA66+GF30%, the connector’s black housing delivers excellent resistance to heat, impact, and chemical exposure. These reinforced engineering plastics maintain structural integrity under extreme temperatures and mechanical stress, making them ideal for under-dash or engine bay installations where durability is paramount.

High-Conductivity Terminals for Clear Signal Transmission

Equipped with terminals made from copper alloy, brass, or phosphor bronze, this connector ensures minimal electrical resistance and consistent contact pressure. These materials are selected for their superior conductivity, corrosion resistance, and spring retention—critical factors in maintaining clean audio signals and reliable data transmission over extended periods.

Ideal for Vehicle Audio Upgrades and Repair Applications

This connector supports a wide variety of uses:

• Replacing damaged male connectors in factory or aftermarket head units

• Building custom adapter harnesses for car stereo retrofits

• Integrating navigation systems, amplifiers, or backup cameras

• Repairing wiring issues in marine or off-road vehicle audio systems

• Creating standardized harnesses for mass installation projects

Its versatility makes it a valuable component for installers, repair shops, and electronic manufacturers alike.

Sealed Design for Protection Against Environmental Factors

While not fully waterproof like some sealed variants, this connector is designed with tight cavity tolerances and robust insulation to resist dust, moisture, and vibration. When properly mated with its counterpart (TS30362-06P-11), it forms a secure connection that withstands the rigors of daily driving and harsh operating environments.

Compliant with Global Automotive and Environmental Standards

Produced in accordance with IATF 16949 (automotive quality management), ISO14001 (environmental responsibility), and RoHS (restriction of hazardous substances), every unit undergoes rigorous testing. A 100% final inspection process verifies terminal alignment, housing integrity, and overall build quality before dispatch, ensuring consistent performance across all production batches.
