The Main/Sub Fuel Tank Transfer Switch is a dashboard‑mounted rocker switch that allows the driver to seamlessly change the fuel supply source between the main and auxiliary fuel tanks. It is a critical component of the Electric Reversing Device, providing a safe and convenient way to manage fuel consumption and balance weight distribution, especially on long‑haul routes where both tanks are used. The switch features an illuminated LED indicator to show which tank is currently active, and its robust construction withstands the vibrations and temperature variations inside the cab.
The Electric Reversing Valve Cab Additional Wire is a dedicated wiring harness that connects the transfer switch to the electric reversing valve located in the chassis. This cable carries the control signals that actuate the valve, directing fuel flow or pneumatic pressure to the desired circuit. It is designed with high‑grade copper conductors and heat‑resistant insulation, ensuring reliable signal transmission and long service life in the demanding under‑cab environment. The wire is pre‑terminated with the correct connectors for a plug‑and‑play installation, reducing downtime during replacement or upgrade.
Our Electric Reversing Device is manufactured to Sinotruk’s original specifications, ensuring seamless integration with the C7H’s electrical and pneumatic systems. The switch and wiring harness are designed to match the factory mounting points and connectors, making replacement quick and error‑free.
The Electric Reversing Device provides positive, click‑type switching with a clear visual indication of the selected tank. This eliminates guesswork and prevents accidental fuel starvation, which can lead to engine stalling. The wiring harness is shielded and sealed to protect against moisture and abrasion.
The complete kit includes the switch and the additional cab wire, along with all necessary clips and connectors. No cutting, splicing, or additional hardware is required. Simply remove the old unit, install the new one, and the Electric Reversing Device is ready to operate.
Both the switch and the wiring harness are built to withstand the harsh conditions of heavy‑duty trucking, including extreme temperatures, vibration, and exposure to fuel, oil, and road spray. The Electric Reversing Device is designed for a long, maintenance‑free service life.
The Electric Reversing Device is an essential upgrade for Sitrak C7H trucks equipped with dual fuel tanks or auxiliary pneumatic circuits. It enables the driver to switch between fuel sources or actuate valves with the flick of a switch, enhancing operational flexibility and reducing the need for manual intervention.
The Main/Sub Fuel Tank Transfer Switch is designed to be mounted in the standard dashboard switch panel, occupying a single slot. Its ergonomic rocker action provides tactile feedback, and the integrated LED clearly indicates the active tank, reducing driver distraction.
The Electric Reversing Valve Cab Additional Wire is made from high‑quality copper conductors with a cross‑section of 1.5mm², ensuring minimal voltage drop over the length of the cab. The insulation is rated to 105°C, making it suitable for the engine bay and under‑dashboard environments. The wire is sheathed in a flexible, abrasion‑resistant loom for additional protection.
A common failure point in older trucks is the deterioration of the original switch contacts or the wiring insulation. Replacing the entire Electric Reversing Device with our genuine kit eliminates intermittent faults and restores reliable tank switching, preventing the inconvenience of running out of fuel unexpectedly.
Installation of the Electric Reversing Device is straightforward and can be completed in under 30 minutes. Begin by disconnecting the battery negative terminal, then remove the old switch from the dashboard and unplug the harness. Connect the new wiring harness to the switch and route it to the valve location, securing it with the provided clips. Reconnect the battery and test the operation.
The switch is rated for 12/24V DC operation, making it compatible with the C7H’s electrical system. Its internal contacts are silver‑plated to prevent corrosion and ensure a low‑resistance path for the control current. The switch housing is made of flame‑retardant nylon, providing additional safety in the event of an electrical fault.
For fleet operators, standardising on this genuine Electric Reversing Device simplifies spare parts management and ensures consistent performance across all vehicles. The switch and harness are identical to the original factory components, eliminating compatibility concerns.
The Electric Reversing Device also finds application in controlling pneumatic reversing valves for auxiliary equipment, such as tipping trailers or hydraulic systems. The cab additional wire can be extended or adapted to suit various valve configurations, making it a versatile solution.
We recommend testing the Electric Reversing Device after installation by activating the switch and listening for the valve click, and verifying fuel flow or pressure change. This confirms that the system is functioning correctly and that all connections are secure.
Should the switch or wire become damaged, our genuine Electric Reversing Device provides a direct replacement that restores full functionality. The use of genuine parts ensures that the electrical characteristics match the vehicle’s original design, preventing issues with fuse ratings or control module compatibility.
