30Pin 2mm 1.8mm Natural Wire Harness Connector with Terminals – Automotive Connector for Select Toyota Car

The TS30101-30P-21 is a 30-pin female wire harness connector designed for seamless integration in automotive audio systems, particularly for select Toyota models. Featuring a natural beige housing and precision-engineered terminal cavities, this connector ensures reliable signal transmission for speaker outputs, power lines, and control circuits. As the female counterpart to the TS30101-30P-11 male plug, it enables clean, factory-style installations when upgrading OEM head units to aftermarket stereos, preserving the original wiring harness and minimizing installation complexity.

Engineered for versatility, the TS30101-30P-21 supports both 2.0mm and 1.8mm terminal sizes, making it compatible with a wide range of crimping tools and wire gauges. Its robust construction and high-temperature resistance make it suitable for use in cars, yachts, UTVs, and other vehicles where durability and stable electrical performance are essential. Whether used in DIY audio kits or commercial harness manufacturing, this connector delivers consistent, long-term reliability in demanding environments.

High-Performance Female Connector for Automotive Audio Systems

The TS30101-30P-21 is specifically designed to serve as the female receptacle in 30-pin automotive harness solutions. Its internal cavity design ensures precise terminal alignment and low contact resistance, supporting stable audio signal and power delivery. The natural-colored housing maintains a factory-original appearance, making it ideal for applications where visual consistency with OEM wiring is important.

This connector is available in two versions: one with a Terminal Position Assurance (TPA) lock and one without. The TPA-equipped variant includes a secondary locking mechanism that prevents terminal withdrawal due to vibration or thermal cycling—common issues in automotive environments. The TPA design also introduces slight structural differences on the connector side, ensuring proper mechanical engagement and long-term reliability in demanding applications such as marine systems, off-road vehicles, and high-performance cars.

Reliable Material Construction for Long-Term Durability

Constructed from either PBT+GF15% or PA66+GF30%, the TS30101-30P-21 offers excellent thermal stability, mechanical strength, and resistance to moisture and chemicals. These engineering-grade plastics ensure the connector maintains its shape and function under extreme temperatures and mechanical stress. The terminals, made from copper alloy, brass, or phosphor bronze, provide superior conductivity and corrosion resistance, contributing to consistent electrical performance over time.
