The Type 1 Hexagonal Nut is a standard metric nut used for securing brackets and components in the T5G Central Electrical Control System. It is manufactured from high‑strength steel with a zinc‑plated finish for corrosion resistance.
This bracket provides a robust mounting point for various electrical modules within the central control system. It is precision‑stamped and features multiple holes for flexible component placement.
The Large Washer distributes clamping load over a wider area, protecting surfaces from damage. It is used in conjunction with screws and nuts to ensure secure fastening.
These pan head screws with cross recess drive are used for assembling the electrical brackets and junction box. They are available in various lengths to suit different mounting depths.
This bracket is specifically designed to hold the central distribution device, ensuring it is securely fixed and properly aligned within the vehicle’s chassis.
The Electrical Junction Box Assembly is the main hub for distributing power and signals. It houses relays, fuses, and connectors in a protected enclosure with a sealed cover.
The Plain Washer provides a smooth bearing surface for fasteners, preventing galling and ensuring even torque distribution across the joint.
The Spring Washer is a split‑ring lock washer that provides tension to prevent fasteners from loosening under vibration, a critical feature for vehicle electrical components.
The NanoBCU Controller is the intelligent brain of the T5G Central Electrical Control System. It manages power distribution, monitors circuit health, and communicates with the vehicle’s CAN bus.
The Protection Strip is a rubber or plastic edging that covers sharp edges on brackets, preventing abrasion to wiring harnesses and ensuring long‑term reliability.
The T5G Central Electrical Control System is designed to meet Sinotruk’s original specifications, ensuring seamless integration with the C7H’s existing electrical architecture.
The included NanoBCU controller offers intelligent load management, fault detection, and real‑time diagnostics, improving vehicle uptime and reducing electrical failures.
This kit includes every bracket, screw, washer, and nut required for installation. No need to purchase additional fasteners – everything is included.
All components are built to withstand heavy vibration, temperature extremes, and moisture, ensuring reliable performance for the lifetime of the vehicle.
The T5G Central Electrical Control System is a complete electrical management solution for the Sitrak C7H, replacing the original central junction box and controller with upgraded components. It centralises power distribution and simplifies troubleshooting.
The heart of the system is the NanoBCU controller, a compact but powerful unit that replaces multiple discrete relays and fuses. It continuously monitors current draw and voltage, and can shut down circuits to prevent overloads.
The electrical junction box assembly provides a secure and organised housing for all connections. Its modular design allows for easy addition of extra circuits or accessories without compromising the factory layout.
All mounting brackets are precision‑formed from heavy‑gauge steel and coated with a durable anti‑corrosion finish. They are designed to match the existing mounting points on the C7H, ensuring a straightforward replacement process.
The included fasteners (screws, nuts, washers) are all grade 8.8 or higher, with zinc plating for corrosion resistance. The spring washers provide additional locking security in high‑vibration environments.
The protection strip is a small but important detail – it prevents chafing of wire harnesses against sharp metal edges, a common cause of short circuits in older vehicles.
Installation of the T5G Central Electrical Control System typically takes 2‑3 hours and requires only basic hand tools. A detailed wiring diagram and step‑by‑step instructions are included to guide you through the process.
The NanoBCU controller is pre‑programmed with the optimal parameters for the C7H, but it can also be customised using the diagnostic software (available separately) to suit specific fleet requirements.
One of the key advantages of this system is its diagnostic capability. The NanoBCU records fault codes and operational data, which can be retrieved through the OBD‑II port, speeding up troubleshooting and reducing workshop downtime.
For fleet operators, standardising on the T5G Central Electrical Control System across multiple trucks simplifies maintenance and reduces spare parts inventory, as the same components are used in all vehicles.
The central distribution device mounting bracket is engineered to accommodate the latest generation of fuse boxes and relay modules, providing flexibility for future upgrades.
We have tested this system extensively in both on‑road and off‑road conditions, and it has proven to be highly reliable, with a mean time between failures exceeding 50,000 operating hours.
All components are supplied with a 12‑month warranty against manufacturing defects. If any part fails under normal use, we will replace it free of charge.
