The 10A Waterproof Fuse Device is a fully sealed, in‑line fuse holder that protects the starter motor wiring against overloads and short circuits. Its robust IP67‑rated housing keeps moisture and dirt away from the fuse element, ensuring reliable protection even in the harshest under‑hood environments. The device accepts standard blade‑type fuses and features a visual indicator for blown fuse detection.
The Plastic Fastening Tape 4.8×360 is a high‑quality cable tie designed for securing wiring harnesses and cables in the engine bay. With a length of 360mm and a width of 4.8mm, it offers excellent tensile strength and UV resistance. The self‑locking mechanism ensures a secure grip, and the smooth edges prevent chafing of wire insulation. This tape is essential for organising the Starter Motor Wires and keeping them clear of moving parts.
This additional wiring harness is designed to connect the 7‑circuit fuse box to the starter motor and other auxiliary circuits. It features pre‑terminated connectors that match the C31 and DZ015 interfaces, simplifying installation. The harness is made from cross‑linked polyethylene‑insulated copper wire, rated for high current and temperature, ensuring safe power distribution to the starter system.
The Starter Positive Power Cable is a heavy‑duty, 70mm² copper cable that carries the main current from the battery to the starter motor. It is equipped with a 280A fuse (BK) and a C09 connector for secure attachment. The cable features a black (BK) protective sheath and is terminated with ring terminals that are crimped and soldered for maximum conductivity and strength. This cable is engineered to handle the high inrush current required for reliable engine cranking.
The Starter Negative Cable is the counterpart to the positive cable, completing the high‑current circuit. It is also a 70mm² cable with a 280A rating, featuring a white (WH022) identification stripe and a C29 connector. This cable connects the starter motor to the vehicle’s chassis ground, ensuring a low‑resistance return path. Its flexible construction allows for easy routing, while the durable insulation protects against heat and abrasion.
The Battery Box Inner Harness is a pre‑assembled wiring loom that connects the battery terminals to the starter cables and the vehicle’s main electrical distribution. Designed for the Howo battery box configuration, it includes fuel‑sensing and power distribution circuits. The harness is wrapped in high‑temperature loom tape and features molded connectors that ensure a watertight seal, preventing corrosion inside the battery box.
Our Starter Motor Wires are manufactured to Sinotruk’s original specifications, ensuring perfect compatibility with the C7H’s electrical architecture. Every cable length, connector type, and terminal size matches the factory design, making replacement straightforward and reliable.
The 70mm² copper cables are rated for continuous high current, supporting the starter motor’s peak draw. The included 280A fuse provides overcurrent protection, preventing damage to the starter and battery in case of a fault.
We supply every component needed for a full starter wiring replacement – positive and negative cables, additional harness, fuse device, fastening tapes, and inner battery harness. No separate purchases are required, saving time and simplifying the job.
All cables are insulated with cross‑linked polyethylene, resistant to oil, heat, and abrasion. The fuse device is fully sealed against moisture, and the fastening tapes are UV‑stabilised. This ensures long‑term reliability in the harsh under‑hood environment.
The Starter Motor Wires kit is a critical electrical upgrade for the Sitrak C7H, addressing the most common failure points in the starting circuit. Over time, original cables can corrode, become brittle, or develop high resistance, leading to slow cranking and starting difficulties.
Our kit uses pure copper conductors with a cross‑section of 70mm², which is the original equipment size for the C7H’s heavy‑duty starter. This ensures that the voltage drop is kept to a minimum, allowing the starter to receive full battery voltage for maximum cranking torque.
The positive cable is equipped with a 280A fuse (BK) that provides protection against short circuits. This fuse is housed in a waterproof holder that prevents corrosion and ensures that the fuse remains operational even in wet conditions.
The negative cable is designed with a white identification stripe (WH022) to distinguish it from the positive cable, reducing the risk of incorrect connection during installation. Both cables feature heavy‑duty ring terminals that are crimped and soldered for a permanent, low‑resistance connection.
The additional 7‑circuit fuse box harness (C31/150/DZ015) is an important addition that allows the starter circuit to be integrated with the vehicle’s main fuse box. This harness provides a direct connection from the battery to the starter relay, bypassing any old or corroded intermediate wiring.
The Battery Box Inner Harness (C09/Howo Battery Box/Fuel) is specifically designed for the Howo battery box configuration used in many C7H trucks. It connects the battery terminals to the starter cables and also includes wiring for fuel‑level sensors and other auxiliary functions, keeping the battery box organised and safe.
The plastic fastening tapes (4.8×360) are provided in a quantity of 20, allowing for thorough cable management. Properly securing the Starter Motor Wires prevents chafing against sharp edges, which is a common cause of electrical shorts.
Installation of the kit is straightforward with basic hand tools. The cables are pre‑cut to the exact lengths required for the C7H chassis, eliminating the need for cutting and crimping. All terminals are factory‑installed, so the installer simply needs to route and connect.
We recommend that the battery be disconnected before starting the installation to prevent accidental short circuits. After installation, a voltage drop test across the starter circuit should be performed to verify that the new cables are delivering full battery voltage.
For fleet operators, replacing aging starter wiring as a preventive measure can significantly reduce roadside breakdowns. The high‑quality materials and precise fitment of our genuine kit ensure that the starting system remains reliable for years.
The 10A waterproof fuse device is an often‑overlooked component; its inclusion ensures that the starter control circuit is protected, not just the main power cable. This additional layer of protection safeguards the starter relay and ignition switch from overloads.
All cables in the Starter Motor Wires kit are manufactured with copper strands that are tinned to resist corrosion, and the insulation is rated to 125°C, making them suitable for the high temperatures found near the engine and exhaust.
We back our Starter Motor Wires with a 12‑month warranty against manufacturing defects. If any cable or component fails under normal use, we will replace it promptly.

Choosing genuine Starter Motor Wires ensures that your C7H starts reliably every time, even in cold weather. Aftermarket cables often use thinner wire or inferior insulation, leading to voltage drop and premature failure.
The kit is also compatible with other Sinotruk models that share the same battery box and starter configuration, making it a versatile spare part for workshops.
We provide a detailed installation guide with torque specifications for all terminal connections. Following these values ensures that the connections remain tight and corrosion‑free.
Maintaining the starter wiring is essential for the overall health of the vehicle’s electrical system. A poor connection can cause voltage spikes that damage sensitive electronics.
