28Pin 2mm 1.6mm Natural Wire Harness Connector with Terminals for Select Toyota Car – Reliable OEM-Style Audio Interface Adapter

The TS30101-28P-21 is a high-quality 28-position female Automotive Connector designed to enable seamless integration of aftermarket audio systems into select Toyota and compatible vehicle platforms. Featuring a natural (off-white) housing, this connector allows for non-invasive stereo upgrades by serving as the mating receptacle for the male plug TS30101-28P-11. It supports full signal transfer across all essential circuits including speaker outputs, power, ground, illumination, and steering wheel control functions—ensuring factory-level functionality is retained after installation. This model is widely used in custom harness kits that eliminate the need to cut or splice original wiring, preserving vehicle integrity and enabling easy restoration if needed.

Ideal for both professional installers and DIY enthusiasts, this connector delivers a secure, vibration-resistant connection critical for long-term reliability in automotive environments. Its design ensures precise terminal alignment and robust locking engagement, minimizing the risk of disconnection due to road shock or thermal cycling. The natural-colored housing provides clear visual distinction from black or colored connectors, making it easier to identify during complex installations. Suitable for use in passenger vehicles, marine yachts, UTVs, and recreational equipment, the TS30101-28P-21 offers durable performance under demanding operating conditions.

Natural Housing for Easy Identification and Factory Matching

The natural (off-white) housing of the TS30101-28P-21 provides a distinct visual identity that simplifies identification among multiple connectors in crowded dashboards. Unlike standard black or blue variants, this color is often used in OEM applications where a neutral yet distinguishable connector is required. It matches factory harnesses in specific Toyota models, ensuring compatibility and aesthetic consistency during stereo upgrades. The housing is engineered to resist yellowing over time, maintaining its clean appearance even under prolonged exposure to heat and UV light found inside vehicle cabins.

Robust Construction for Long-Term Reliability

Constructed from reinforced thermoplastic materials—PBT+GF15% or PA66+GF30%—this connector delivers superior resistance to mechanical stress, thermal cycling, and chemical exposure. These engineering-grade plastics maintain structural integrity across extreme temperatures (-40°C to +120°C), preventing warping or cracking. The internal Terminals are precision-made from copper alloy, brass, or phosphor bronze, offering excellent conductivity, low contact resistance, and strong corrosion resistance. This combination ensures stable electrical performance and long service life, even in harsh environments such as marine vessels, off-road vehicles, and high-mileage automobiles.
