Manufactured from high-strand copper conductors, heat-resistant thermoplastic insulation and a reinforced outer jacket, the 080V25413-6089 Injector Wiring Harness is built to exact OEM dimensions. Its robust construction resists vibration, abrasion, diesel fuel, oil and temperature extremes, delivering dependable performance under the constant electrical loads and thermal cycling of commercial truck engine operation.
OEM 080V25413-6089 • Injector signal delivery • Sealed connectors • Vibration resistant • Direct OEM fit
The 080V25413-6089 Injector Wiring Harness is a critical electrical component in the engine management system of SINOTRUK Howo trucks. It carries high-current pulses from the engine ECU to each fuel injector solenoid, controlling injection timing and fuel quantity for optimal combustion and emissions performance.
This 080V25413-6089 harness is precision-manufactured to exact OEM dimensions. The copper conductors are sized for the correct current rating, the insulation is formulated for high temperatures and diesel fuel exposure, and the molded connectors are sealed against dust and moisture. The harness includes all necessary terminals and protective sleeving.
Common signs that an injector wiring harness needs replacement include misfiring cylinders, rough idle, engine power loss, excessive black smoke, poor fuel economy, blown fuses and stored fault codes for injector circuit faults. Fitting a new 080V25413-6089 harness restores correct injector operation and reliable engine performance.
Whether you are repairing a faulty injector circuit, replacing a damaged harness or carrying out preventive maintenance on a fleet of Howo trucks, the 080V25413-6089 Injector Wiring Harness delivers the quality, reliability and durability that SINOTRUK Howo professionals expect.
The 080V25413-6089 Injector Wiring Harness is designed for SINOTRUK Howo trucks, with primary compatibility across the A7, T7H, HOWO 371 and HOWO 380 series. It is a direct OE replacement, so it connects to the factory injectors and engine ECU without modification.
This harness is essential in applications where reliable fuel delivery and engine performance are critical, such as long-haul transport, construction, mining and municipal service. In these duties, the harness must deliver stable current without voltage drop and resist vibration, fuel exposure, heat and contamination.
When replacing the injector wiring harness, it is recommended to inspect the fuel injectors, engine ECU, valve cover gasket, fuse, relay and main engine harness for wear or damage. The 080V25413-6089 is designed to work with the factory engine management system, ensuring correct current delivery and reliable operation.
For fleets with multiple HOWO trucks, standardising on the 080V25413-6089 Injector Wiring Harness simplifies engine repair inventory and ensures the correct harness is available for scheduled maintenance or emergency repairs.
Replacing the 080V25413-6089 Injector Wiring Harness is a moderately simple procedure that requires basic electrical and mechanical knowledge. This work should be performed by a qualified technician. Begin by disconnecting the battery negative terminal to prevent accidental short circuits.
Remove the engine cover or valve cover as needed to access the injectors. Disconnect the old harness from each injector and the engine ECU, taking note of the routing and any retaining clips. Withdraw the old harness and inspect the connectors for corrosion, melting or damage.
Route the new 080V25413-6089 harness along the original path and secure it with the factory clips. Connect each injector plug and the ECU connector until they click into place. Reconnect the battery and clear any fault codes using a diagnostic tool. Test the engine through its full operating range.
For ongoing maintenance, periodically check that the harness is securely routed away from sharp edges, hot exhaust parts and moving components, and that the connectors are clean and dry. If engine misfire recurs, inspect the injectors and ECU before replacing the harness again.
The 080V25413-6089 Injector Wiring Harness is manufactured in an ISO 9001-certified facility using high-quality copper conductors and automated crimping processes. Raw materials are sourced from certified suppliers and undergo incoming inspection for conductor resistance, insulation thickness and terminal plating.
Each harness is assembled on precision lines and then tested for continuity, insulation resistance and high-potential withstand. The terminals are pull-tested to ensure secure crimps, and the outer jacket is inspected for correct fit and finish. Every unit is subjected to a functional current test before packing.
Random samples from each production batch undergo environmental testing, including thermal cycling, vibration, diesel immersion and fluid exposure, to validate long-term reliability in heavy-duty truck applications. These tests ensure the harness continues to perform in the harsh conditions experienced by SINOTRUK Howo vehicles.
We back the 080V25413-6089 with a comprehensive 12-month warranty against material and workmanship defects. Our rigorous quality control ensures that every injector wiring harness delivers the same fit, function and durability as the original factory component.
The 080V25413-6089 Injector Wiring Harness is a vital component for maintaining reliable fuel delivery, engine performance and vehicle uptime on your Howo truck. A faulty harness causes misfiring, power loss and difficult starting, especially under heavy loads or in cold weather.
Manufactured from high-quality copper with heat-resistant insulation and sealed connectors, the 080V25413-6089 offers outstanding reliability, current stability and long-term durability. Its direct-fit design ensures straightforward installation and immediate compatibility with the factory engine management system.
