The Socket is a robust, weather‑sealed connector that serves as the vehicle‑side interface for the trailer EBS system. It features gold‑plated pins for low resistance and a durable cover that protects against dust and moisture, ensuring reliable communication between the truck and trailer.
The Hexagon Head Bolt is a high‑strength M8 fastener used to securely mount the socket and the Trailer EBS Connector and Wiring Harness components to the vehicle chassis. Its hexagonal head allows for easy tightening with standard tools.
The Spring Washer is a split‑ring lock washer that provides tension to prevent the Hexagon Head Bolts from loosening under vibration. It is essential for maintaining the integrity of the mounting assembly in the demanding heavy‑truck environment.
The Type 1 Hexagonal Nut is the matching nut for the Hexagon Head Bolt, providing a secure and reliable fastening solution. It is zinc‑plated for corrosion resistance and is designed to withstand high clamping forces.
The Trailer EBS Power Harness Assembly (4500) is a pre‑terminated wiring harness that connects the vehicle’s EBS control unit to the trailer socket. With a length of 4500mm, it provides ample reach for most trailer configurations and includes high‑quality conductors with XLPE insulation for reliable power and signal transmission.
Our Trailer EBS Connector and Wiring Harness is manufactured to Sinotruk’s original specifications, guaranteeing perfect compatibility with the Sitrak C7H EBS system. The socket and harness are designed to work seamlessly with the vehicle’s electronic braking architecture.
The gold‑plated pins and high‑quality wiring ensure low resistance and stable signal transmission, critical for the correct operation of the trailer EBS. This reduces the risk of braking faults and improves overall safety.
This kit includes everything needed for installation – the socket, harness, bolts, spring washers, and hex nuts. No additional parts to source, saving time and simplifying the replacement process.
All components are designed to withstand the harsh conditions of heavy truck operation, including moisture, road salt, and extreme temperatures. The socket’s sealed cover and the harness’s robust insulation ensure long‑term reliability.
The Trailer EBS Connector and Wiring Harness is a critical component for modern commercial vehicles equipped with Electronic Braking Systems. It provides the electrical interface between the truck and trailer, enabling real‑time communication of braking commands and diagnostic data.
The socket is designed to meet ISO 7638 standards, ensuring compatibility with all modern trailers equipped with EBS. Its robust construction and secure locking mechanism prevent accidental disconnection during operation.
The Trailer EBS Power Harness Assembly (4500) is specifically engineered for the Sitrak C7H, with a length of 4500mm that accommodates most trailer combinations. It is pre‑terminated with the correct connectors for a plug‑and‑play installation, reducing workshop time.
The included fasteners – Hexagon Head Bolts, Spring Washers, and Type 1 Hexagonal Nuts – are all made from high‑grade steel with corrosion‑resistant plating. They ensure that the socket remains firmly mounted even under the high vibration levels typical of heavy‑duty trucks.
A common cause of trailer EBS faults is a poor electrical connection due to corroded pins or damaged wiring. Replacing an old or damaged socket and harness with our genuine Trailer EBS Connector and Wiring Harness restores full braking performance and eliminates intermittent faults.
The harness uses high‑quality copper conductors with cross‑linked polyethylene (XLPE) insulation, which offers superior resistance to heat, abrasion, and chemicals. This ensures that the wiring remains flexible and durable throughout the vehicle’s service life.
The socket’s cover is designed to be easily opened and closed for connection and disconnection, while still providing a tight seal against moisture and dust. This is particularly important for trucks that operate in wet or muddy conditions.
We recommend inspecting the Trailer EBS Connector and Wiring Harness periodically for signs of wear, such as cracked insulation, bent pins, or corrosion. If any damage is found, replacing the affected components with our genuine parts will restore system integrity.
For fleet operators, maintaining a consistent and high‑quality Trailer EBS Connector and Wiring Harness across all trucks simplifies diagnostics and reduces spare parts inventory. Our kit provides a standardized solution that can be used on any C7H model.
The Trailer EBS Connector and Wiring Harness is compatible with all Sitrak C7H variants, including those with 4×2, 6×4, and 6×2 drivetrains. It is also suitable for use on other Sinotruk models that share the same EBS architecture.
