16Pin Female Grey Car Aftermarket Stereo Audio Connector 33472-1602 – TS30359-16P-21-1 High-Performance Plug for Reliable Vehicle Integration

The TS30359-16P-21-1 is a 16-pin female grey Automotive Connector designed for seamless integration in aftermarket stereo installations and OEM-compatible wiring systems. Serving as the female counterpart to the TS30359-16P-11-1 male housing, this component ensures stable, low-resistance electrical connections for audio, control, and data signals in modern vehicles. Ideal for use with the 33472-1602 interface, it enables clean, no-cut upgrades for car stereos while preserving factory features such as steering wheel controls, backup cameras, and vehicle diagnostics. Its neutral grey housing offers excellent visual contrast in complex harness bundles, making it a preferred choice for professional installers and DIY enthusiasts working on cars, yachts, UTVs, and specialty vehicles.

Engineered for Precision in Aftermarket audio systems

The TS30359-16P-21-1 is specifically designed to support high-fidelity audio upgrades without compromising vehicle functionality. When used in stereo replacement kits, it eliminates the need for cutting or splicing factory wires, allowing for a clean, reversible installation. Its 16-pin female configuration ensures full compatibility with the 33472-1602 interface, enabling accurate signal routing for audio output, microphone input, lighting control, and communication buses like CAN or LIN. This makes it an essential component for maintaining OEM-level performance while upgrading to modern infotainment systems.

Superior Housing Materials for Long-Term Durability

Constructed from either PBT+GF15% or PA66+GF30%, the connector housing delivers excellent resistance to heat, impact, and chemical exposure. These reinforced thermoplastics maintain their structural integrity under continuous thermal cycling—from sub-zero winters to scorching engine bay temperatures—ensuring a secure fit over the vehicle’s lifespan. The grey color is molded-in, not painted, preventing fading or chipping even after years of service. This durability is critical for applications in harsh environments such as off-road vehicles, marine dashboards, and industrial utility transport.

Mat-Seal Technology for Unmatched Environmental Protection

Each terminal cavity in the TS30359-16P-21-1 features a factory-installed mat seal that remains closed until a terminal is inserted. This design prevents moisture, dust, and corrosive contaminants from entering the connector body, significantly reducing the risk of electrical failure. If a circuit is later deactivated, a sealing plug can be inserted into the vacant position to maintain the overall environmental protection of the assembly. This level of sealing is vital for under-dash, door-mounted, or exterior-facing installations where exposure to humidity and condensation is common.

High-Conductivity Terminals for Stable Signal Transmission

The internal contacts are crafted from premium copper alloy, brass, or phosphor bronze—materials known for their superior electrical conductivity, mechanical resilience, and resistance to oxidation. These terminals are precision-stamped and formed to ensure consistent contact pressure and minimal voltage drop, even after repeated mating cycles. The result is reliable power delivery and noise-free signal transmission, essential for high-quality audio systems and sensitive control modules.

Wide Range of Automotive and Marine Applications

While primarily used in aftermarket stereo harnesses, this connector is also suitable for a variety of other applications, including:

• Factory-to-aftermarket interface adapters

• Vehicle control unit extensions

• Lighting and HVAC system integration

• Marine audio and navigation systems

• UTV and specialty vehicle wiring solutions

Its modular design and compatibility with standard crimping tools make it easy to integrate into custom harness builds.
