Precision-Engineered Replacement for 33472-0803 Factory Audio Connectors

The TS30359-08P-21-2 is a direct-fit brown housing connector that replicates the exact mechanical and electrical specifications of the original 33472-0803 used in numerous vehicle infotainment systems. Its distinctive brown color allows for quick visual identification during installation or troubleshooting, reducing errors in multi-harness environments. This connector is ideal for replacing damaged OEM units, building custom audio harnesses, or extending wiring for head units, amplifiers, and navigation systems—offering a plug-and-play experience without the need for modification.

High-Strength Housing for Demanding Vehicle Environments

Built from either PBT+GF15% or PA66+GF30% reinforced thermoplastics, this connector offers excellent resistance to heat, impact, and chemical exposure. The glass-filled material ensures long-term dimensional stability and prevents warping or cracking, even under continuous vibration and temperature fluctuations. Whether installed under the dashboard, near the engine, or in marine applications, the TS30359-08P-21-2 maintains structural integrity and protects internal Terminals from environmental damage.

8-Pin Female Design for Comprehensive Audio and Control Signal Routing

With eight precisely molded cavities, this housing supports full signal routing for factory audio systems, including power, ground, speaker outputs, remote turn-on, and accessory control lines. It is compatible with copper alloy, brass, and phosphor bronze terminals, ensuring low contact resistance and reliable conductivity over time. This makes it suitable for use in car stereo retrofits, amplifier installations, marine audio upgrades, and UTV entertainment systems—where consistent signal integrity is essential for optimal performance.

Designed to Mate with TS30359-08P-11-2 Male Connector

This female housing is engineered to securely lock with the TS30359-08P-11-2 male plug, forming a polarized, vibration-resistant connection. The integrated mat-seal groove allows for the addition of a rubber gasket, enhancing protection against moisture, dust, and salt spray. Once mated, the pair creates a sealed, durable junction ideal for use in harsh environments such as boats, off-road vehicles, and industrial equipment—where loose or corroded connections can lead to intermittent faults or system failure.

Common Applications in Automotive, Marine & Specialty Vehicles

Typical use cases include:

• Replacing damaged 33472-0803 connectors in factory car stereos

• Building extension harnesses for head unit and amplifier installations

• Creating custom wiring solutions for yacht and marine audio systems

• Integrating aftermarket components into UTVs, ATVs, and off-road vehicles

• Supplying bulk connectors for audio installers, repair shops, and distributors

Its compatibility with standard crimp tools and terminals makes it accessible for both professional installers and DIY users.
