PRODUCTS LINEUP
Modern vehicles are equipped with an ever-growing number of electronic components, performing far beyond the basic functions of driving, turning, and stopping. To power and control these systems, automotive wiring harnesses play an essential role—acting as the vehicle’s nervous and circulatory system. A wire harness consists of bundled wires protected and structured by terminals, connectors, clamps, and sheaths. It is responsible for transmitting power and signals across the vehicle with stability and precision.
At TSCN, we specialize in wiring harnesses for aftermarket car interface systems, offering tailored solutions for efficient and non-invasive integration of audio, navigation, and control systems. Our product range includes:
These harnesses enable plug-and-play connectivity between factory wiring and aftermarket head units, preserving the integrity of the vehicle’s original systems. Popular models like the 22-pin and 26-pin T-Harnesses are ideal for audio upgrades and steering wheel control modules, ensuring fast installation and system compatibility.
Designed to enhance multimedia accessibility, these harnesses allow smooth integration of external devices via USB or AUX input. Our best-selling models—such as Mazda AUX USB Adapters and Mini USB + Audio combo harnesses—support data transmission and audio playback with OEM-level fit and finish.
Essential for radio and infotainment system replacements, antenna adapter harnesses bridge compatibility between aftermarket head units and factory antennas. With options like Fakra connector types and Toyota-specific versions, these harnesses ensure strong, clear signal reception and minimal interference.
These harnesses are engineered for non-destructive installations. Perfect for adding smart modules, CAN signal extraction, or remote starters, products like the 16-pin seamless adapter ensure full functionality while maintaining the vehicle’s original wiring untouched—ideal for high-end retrofits and system expansions.
By delivering reliability, compatibility, and ease of installation, our wire harness solutions help automotive professionals and DIY users alike build smarter, safer, and more connected vehicles.

APPLICATION
1. T-Harness
Best-Fit Scenario: Non-destructive installation when replacing the factory head unit or upgrading the central control system
T-Harnesses are ideal for scenarios where users upgrade their factory radio to an aftermarket Android touchscreen, Apple CarPlay unit, or navigation display. These harnesses allow direct plug-and-play connection with the vehicle’s original wiring—no cutting, no splicing—while preserving OEM features like steering wheel control, reverse camera input, or door signal alerts. It’s the preferred solution for car audio shops, multimedia upgrade centers, and professional installers.
2. AUX / USB Adapter Harness
Best-Fit Scenario: Adding AUX or USB input to older vehicles without modifying the dash
These harnesses are perfect for vehicles that lack modern audio input ports. Users can easily add 3.5mm AUX or USB input for music streaming, device charging, or smartphone integration. It’s especially useful for budget-friendly entertainment upgrades where the main head unit remains unchanged. Ideal for DIY users, ride-share vehicle owners, or older-model upgrades.
3. T-Harness
Best-Fit Scenario: Ensuring FM/AM radio signal compatibility after replacing the stereo system
Antenna adapters are essential when replacing the factory radio and the new unit has a different antenna port. These harnesses ensure uninterrupted access to FM/AM broadcasts, traffic updates, and local stations. They are widely used in aftermarket stereo replacements where radio reception continuity is a must—especially for daily commuters and fleet users who rely on radio for information.
4. Seamless Adapter Harness
Best-Fit Scenario: Installing smart modules like remote starters or DVRs without cutting OEM wires
Seamless adapter harnesses are best used in advanced retrofit projects where components such as remote starters, GPS trackers, CAN control boxes, or DVR systems are added. These harnesses allow precise access to power, ignition, and data lines using OEM-style connectors, enabling non-invasive installation. Perfect for high-end vehicle customization, fleet upgrades, or warranty-sensitive installations.
