12Pin Female Grey Car Aftermarket Stereo Audio Connector 33472-1202 – TS30359-12P-21-1 High-Reliability Housing for Automotive Audio & Control Harnesses

For automotive technicians, audio installers, and OEM manufacturers, the TS30359-12P-21-1 delivers a dependable and durable solution for modern vehicle wiring systems. Designed as a direct replacement for original equipment 33472-1202, this 12-pin female connector in sleek grey housing is engineered to ensure stable, long-lasting connections in car audio, infotainment upgrades, and control modules. As the mating counterpart to the TS30359-12P-11-1 male plug, it forms a secure, sealed interface that resists vibration, moisture, and electrical failure—making it ideal for use in aftermarket stereo installations, marine environments, and off-road vehicles where reliability is paramount.

Designed for Precision Fit in Aftermarket Audio Installations

The TS30359-12P-21-1 grey female connector is specifically engineered to meet the dimensional and electrical requirements of OE 33472-1202, making it a seamless upgrade or replacement for factory audio systems. Its 12-pin configuration supports a wide range of audio, power, and control signals, commonly used in head unit connections, amplifier interfaces, and multi-speaker setups. The grey housing provides clear visual identification, helping technicians quickly match connectors during installation and reducing the risk of incorrect mating in complex harness environments.

Mat-Sealed Protection for Harsh Operating Conditions

Each terminal cavity is pre-fitted with a mat seal and protective diaphragm that activates when a wire is inserted, forming a waterproof seal around the insulation. This advanced sealing technology prevents moisture, dust, and salt from entering the connector body—critical for vehicles exposed to rain, humidity, or marine environments. Whether installed in a car dashboard, boat console, or utility vehicle control panel, this connector ensures long-term signal integrity and minimizes the risk of corrosion-related failures.

Robust Two-Piece Housing with Secondary Lock Mechanism

Engineered for high-vibration applications, the TS30359-12P-21-1 features a two-piece housing design with a secondary wedge lock. After Terminals are inserted into the primary housing, the wedge is engaged to secure all contacts in place. This dual retention system prevents terminal backout caused by engine vibration, road shock, or repeated thermal expansion—common issues in automotive and off-road systems. The result is a stable, reliable connection that maintains electrical continuity over time.

Durable Thermoplastic Construction for Long Service Life

Made from either PBT+GF15% or PA66+GF30%, the housing offers excellent resistance to heat, impact, and chemical exposure. These glass-reinforced materials maintain their mechanical strength and dimensional stability across a wide temperature range, ensuring reliable performance in extreme climates. The grey color provides UV resistance and helps maintain a clean, professional appearance even after prolonged use.

Versatile Terminal Options for Custom Wiring Projects

This connector supports copper alloy, brass, and phosphor bronze terminals, allowing users to optimize for conductivity, cost, and durability. Its standardized layout is compatible with common crimping tools and widely used in aftermarket stereo upgrades, factory harness repairs, and custom wire harness manufacturing. Whether you're building a new harness or replacing a damaged connector, the TS30359-12P-21-1 offers flexibility and reliability for both professional and DIY applications.

Part of a Complete Connector System for Automotive Use

The TS30359-12P-21-1 is designed to mate with the TS30359-12P-11-1 male plug, forming a secure, sealed connection ideal for vehicle audio, control modules, and sensor wiring. It is part of a broader family of connectors available in multiple pin counts and colors (black, green, brown, grey) to support various system configurations. We also supply matching male housings and individual terminals upon request, providing a complete solution for wiring harness builders and repair technicians.
