Why Green? Color-Coded Reliability for Complex Installations

Color plays a crucial role in reducing human error during vehicle wiring and repair. The green housing of the TS30359-16P-21-3 provides instant differentiation from standard black, white, or grey connectors commonly found in dashboards and control units. This visual cue is especially valuable in multi-harness setups where misconnections can lead to system malfunctions or component damage. Whether used in a BMW, Mercedes, or aftermarket audio kit, the green shell ensures fast, accurate identification—making it a favorite among professional installers and fleet service teams.

Built to Survive Real-World Automotive Conditions

Vehicles subject connectors to constant vibration, thermal cycling, moisture, and chemical exposure. The TS30359-16P-21-3 is engineered to withstand these challenges with reinforced housing materials—either PBT+GF15% or PA66+GF30%. Both materials offer high tensile strength, excellent dimensional stability, and resistance to warping under prolonged heat exposure. The green pigment is integrated at the polymer stage, ensuring the color remains vibrant and consistent, even after years of use in direct sunlight or under harsh cleaning agents.

Mat-Sealed Design for Superior Environmental Protection

Each terminal cavity features a factory-installed rubber diaphragm that seals tightly around the inserted wire. This mat-seal technology prevents moisture, dust, and corrosive gases from entering the connector body, significantly reducing the risk of short circuits, signal loss, and terminal corrosion. Unused positions remain sealed until activated, and optional cavity plugs are available to maintain protection when circuits are reconfigured. This makes the connector ideal for use in door modules, under-dash control units, marine electronics, and off-road vehicle systems where environmental exposure is a concern.

Perfect for Aftermarket Audio and OEM Integration

When upgrading a factory stereo system, maintaining compatibility with vehicle electronics is critical. The TS30359-16P-21-3 enables true plug-and-play connectivity, eliminating the need for wire cutting or soldering. It supports full signal retention for audio output, microphone input, CAN bus communication, and accessory power, ensuring all factory features remain functional after installation. This level of integration is essential for preserving warranty eligibility and ensuring a professional-grade upgrade experience.

High-Performance Terminals for Consistent Signal Integrity

The internal contacts are made from high-purity copper alloy, brass, or phosphor bronze—selected for their excellent conductivity, spring retention, and resistance to oxidation. These terminals are precision-formed to ensure optimal mating force and minimal contact resistance, delivering stable power and noise-free audio signals. Whether used in a high-wattage amplifier harness or a sensitive control module, the result is reliable, long-term performance under continuous load.

Applications Beyond Automotive Audio

While widely used in stereo upgrade kits, this connector is also suitable for:

• Vehicle lighting control modules

• Sensor signal distribution blocks

• Marine navigation and entertainment systems

• UTV and specialty vehicle wiring harnesses

• Factory extension cables for service and repair

Its modular design and compatibility with standard crimp tools make it a versatile solution for custom wiring projects.
