30 Way Female Black Automotive Connector with TPA – TS30358-30P-21 (Compatible with 33268470)

The TS30358-30P-21 is a 30-pin female automotive electrical connector designed for high-reliability signal transmission in vehicle audio and control systems. Engineered as a direct replacement for OEM connector 33268470, this black-colored housing unit features an integrated Terminal Position Assurance (TPA) mechanism that locks Terminals securely in place, preventing disconnection due to vibration or mechanical stress. As the female counterpart to the male plug TS30358-30P-11, it enables seamless integration into factory-installed harnesses for cars, marine yachts, UTVs, and specialty vehicles, supporting non-invasive stereo upgrades and system modifications.

The sleek black housing provides a modern, low-visibility profile that blends into existing wiring looms, minimizing visual clutter during installations. Its precise molding ensures accurate terminal alignment and smooth mating, delivering consistent electrical performance and long-term durability in demanding automotive environments.

TPA-Enhanced Reliability for Harsh Environments

The built-in Terminal Position Assurance (TPA) system in the TS30358-30P-21 ensures that each terminal remains firmly seated within the connector housing, even under continuous vibration or thermal cycling. This secondary lock is crucial for maintaining stable Electrical Contact in off-road vehicles, marine applications, and high-performance automobiles where mechanical stress is common. The TPA also simplifies quality checks during assembly, allowing technicians to visually confirm full terminal engagement before final installation, reducing the risk of intermittent faults.

High-Performance Materials for Long-Term Use

The connector body is constructed from either PBT+GF15% or PA66+GF30%, both of which offer excellent heat resistance, mechanical strength, and dimensional stability. These reinforced thermoplastics ensure the housing maintains its shape and sealing integrity under extreme temperature variations. The internal terminals are made from high-conductivity copper alloy, brass, or phosphor bronze, providing low electrical resistance and strong resistance to oxidation, ensuring consistent signal transmission for audio, power, and data lines.

With the rising usage of wire harnesses, thanks to their efficiencies and plethora of advantages, the demand for a variety of different harnesses is also on the rise. Our company are focuing on this market for more than 20years.

The sole purpose of a connector type wire harness is to transmit electrical signals from the wire harness to the power source. Connectors comprise of different plugs and jacks, the design being based on the function and performance required. There are essentially two main types of wire harness connectors – male and female, which serve to provide the necessary junctions between the many different elements of the wire harness.This Aptiv 30way connector with TPA are made by ourself in three color, Grey, Black, White. We have the female one, male one and the mated terminals.
