CUMMINS
4952746 / 2864510 ETR Control Module Wiring Harness (HARNESS,ETR CNT MDL WRG) is a dedicated electronic control wiring assembly for CUMMINS series diesel engines. As the key signal and power transmission carrier of the engine electronic control system, it connects the electronic control module, various sensors and executive components. It ensures real-time, accurate and stable transmission of engine operation data, fuel injection signals and power supply signals.
This wiring harness effectively solves common engine faults caused by aging wires, damaged insulation layer, oxidized connectors and poor contact, such as unstable engine operation, intermittent flameout, fault code flashing, power attenuation and abnormal fuel consumption.
1. High-Grade High-Temperature Resistant Wire Core
Adopts special automotive-grade high-temperature and oil-resistant wire materials, which can adapt to high-temperature, greasy and dusty harsh environments in the engine compartment. It is not easy to age, harden or crack after long-term operation, ensuring long-term stable circuit transmission.
2. Precision Original-Matching Connector
The terminals and plugs are precisely machined in accordance with original specifications, with good electrical conductivity and anti-oxidation performance. It can effectively avoid poor signal contact, virtual connection and circuit interruption caused by engine vibration, ensuring zero-delay signal transmission.
3. Professional Protective Structure Design
Equipped with high-quality corrugated pipes, insulating wrapping tapes and fixed buckles, the overall protection performance is upgraded. It can effectively resist friction, pull and extrusion during engine operation, prevent wire damage and short circuit faults, and greatly improve the service life of the harness.
4. Strong Anti-Interference Performance
Optimized wiring layout and shielding design reduce electromagnetic signal interference, ensure the accuracy of fuel injection, speed and temperature signal transmission, and avoid engine jitter and power disorder caused by signal deviation.
5. Waterproof and Dustproof Durability
The connector has excellent waterproof and dustproof performance, which can resist the erosion of humid air, sediment and engine oil, and adapt to the complex working conditions of construction machinery and heavy trucks.
6. Standard Interchangeable Specification
Dimension 50cm*40cm*10cm, weight 2.9KG. The overall length, wiring sequence and hole position of the harness are completely matched with the original CUMMINS engine, realizing direct plug-and-play replacement without cutting or modifying the circuit.
7. Strict Factory Electrical Testing
All harnesses pass strict continuity test, insulation resistance detection, voltage resistance test and plug fitting inspection. The batch quality is stable, which is very suitable for engine overhaul, fleet maintenance and bulk procurement by auto parts distributors.
