27-Way Male Wire To Wire Connector Natural Automotive Connector with Terminal for Toyota Car – Reliable OEM-Style Audio Signal Adapter

The TS30378-27P-11 is a 27-position male automotive connector designed for seamless integration of aftermarket audio systems into select Toyota and compatible vehicle platforms. Featuring a natural (off-white) housing, this connector serves as the male plug that mates with the female receptacle TS30378-27P-21, enabling a non-invasive method to connect upgraded stereos without cutting or splicing factory wiring. This solution preserves the original harness, allowing for easy restoration or future upgrades while maintaining a clean, professional installation. Commonly used in custom wire harness kits, this connector supports full signal transmission for speaker outputs, power, ground, illumination, and steering wheel control functions.

Engineered for durability and precision, the TS30378-27P-11 ensures stable electrical performance in demanding automotive environments. Its Male Terminal design provides secure contact engagement, minimizing the risk of disconnection due to vibration or thermal cycling. The natural-colored housing offers clear visual identification during installation and matches OEM harnesses found in specific Toyota models, ensuring both functional and aesthetic compatibility. Suitable for use in passenger cars, marine yachts, UTVs, and off-road vehicles, this connector delivers long-term reliability where consistent signal integrity is essential.

Natural Housing for OEM Matching and Easy Installation

The natural (off-white) color of the TS30378-27P-11 housing is specifically chosen to match factory-installed harnesses in certain Toyota models, ensuring a seamless fit during audio upgrades. This color provides better visibility than black connectors in confined dashboard spaces, helping technicians avoid misalignment or incorrect mating. It also resists yellowing over time, maintaining a clean appearance even after prolonged exposure to heat and sunlight. The housing design includes precise alignment guides and a locking mechanism to ensure secure, repeatable connections that withstand vehicle vibration and thermal expansion.

Durable Construction for Long-Term Performance

Built using high-strength thermoplastic materials—PBT+GF15% or PA66+GF30%—this male connector offers excellent resistance to impact, heat, and chemical exposure. These reinforced plastics maintain structural integrity across a wide temperature range (-40°C to +120°C), preventing deformation or cracking. The internal Terminals are made from copper alloy, brass, or phosphor bronze, delivering superior electrical conductivity, low contact resistance, and strong corrosion resistance. This combination ensures reliable signal transmission and long service life, making it ideal for use in harsh environments such as marine vessels, off-road vehicles, and high-mileage automobiles.
