Installation and Maintenance: Ensuring Secure and Reliable Wiring Harnesses Installation Steps： 1.Confirm Connector Type: Match the wiring harness to the vehicle and trailer connectors. Secure the wiring harness: Use clips or zip ties to secure it, preventing loosening or wear during travel. 2.Check connections: Ensure connectors are fully seated and electrical equipment (e.g., lights) functions properly. Maintenance Key Points Regular inspection: Monthly checks for loose or corroded connectors; clean away debris. Avoid aging: Prevent prolonged exposure to sunlight or humid environments. Prevent wear: Steer clear of sharp objects during travel to avoid damaging the harness outer sheath.

As a professional manufacturer of wire harnesses, we pursue high-quality products to meet customer requirements, select superior wire harness materials, and create first-class wire harness products Wire selection: Wires that meet the vehicle's electrical requirements should be chosen. Generally, wires with sufficient cross-sectional area and good insulation performance should be selected. Avoid damage: When wiring, be sure to avoid damaging the insulation layer of the wires to prevent short circuits. Inspection and Testing: After all wiring work is completed, a thorough inspection should be carried out to ensure that there are no exposed wires, loose joints or other issues. After reconnecting the power supply, test whether the lights are working properly, including brightness, flashing frequency, etc.  

Environmental adaptability: Capable of handling complex working conditions Heat resistance and corrosion resistance The wire harness material needs to be adaptable to extreme temperatures (such as -40℃ to 125℃) and chemical corrosion (such as salt spray and oil stains). Solution: Cross-linked polyethylene (XLPE) insulation layer is adopted, with a temperature resistance grade of up to 150℃, and the service life is 5 to 10 years longer than that of PVC. Waterproof and dustproof The connector adopts an IP67 or higher protection grade and prevents moisture from entering through sealing rings or potting compound. Case: The wiring harness of outdoor photovoltaic inverters needs to pass the salt spray test (96 hours without corrosion) to ensure long-term use in coastal areas. Anti-vibration and wear-resistant The spacing of the wire harness fixing points should be no more than 300mm. They should be protected by corrugated tubes or fabric sleeves to prevent loosening of the connection due to vibration. Test standard: Automotive wiring harnesses must pass the vibration table test (frequency 10-500Hz, acceleration 5g, lasting for 10 hours).

The core function of corrugated pipes: 1. Mechanical protection: During the operation of a snowplow, the vibration is intense. The corrugated pipe absorbs the impact force through its concave-convex corrugated structure, preventing the wiring harness from being damaged due to friction or impact, and providing excellent protection   2. Environmental isolation: Corrugated pipes have the characteristics of low-temperature resistance and chemical corrosion resistance 3. Electromagnetic shielding: Ensuring the stability of signal transmission   Our advantages are: With professional wiring harness engineers, our own factory and a large number of wiring harness technicians, we are committed to creating high-quality wiring harnesses 2.

Function：  1.Power transmission: Transmit the power from the power source (such as a battery or generator) to the signal light to ensure its normal operation.   2.Signal transmission: Transmit the signals from the control module (such as the body control unit BCM) to the signal lights to achieve functions such as on-off control and flashing frequency control of the signal lights. For instance, when the driver turns on the turn signal switch, the BCM transmits the signal to the turn signal through the wiring harness, causing it to flash at the set frequency.   3.Ensuring safety: By accurately transmitting power and signals, it ensures that traffic lights can operate normally at critical moments, providing an important guarantee for driving safety. For instance, when a vehicle brakes, the brake lights come on to alert the driver of the vehicle behind to slow down and give way. The turn signal flashes when a vehicle is turning or changing lanes, informing other road users of the vehicle's driving intention.   Important：We have our own R&D team, with professional wiring harness engineers dedicated to developing and manufacturing for customers.

As a professional wiring harness manufacturer, we are committed to producing high quality products. New energy equipment wiring harness, Automotive wiring harnesses and snow plow wiring harnesses are our forte! Wiring harness structure and function： Power transmission wiring harness Responsible for the connection between the battery and the motor, as well as the drive module, it needs to withstand high currents (such as 24V DC motor drive), and the wire material should have low resistance and high-temperature resistance (usually above 80℃) characteristics. Some high-end models adopt copper-silver-plated wire cores to reduce energy consumption. Signal control wiring harness When connecting the main control board to sensors (such as lidar and collision sensors), external electromagnetic interference (EMI) needs to be shielded. For instance, twisted-pair cable structures or aluminum foil wrapping are adopted to ensure the stability of signals such as gyroscopes and cliff sensors. Sensor connection wiring harness For precision components such as infrared sensors and cameras, the wiring harnesses need to have high flexibility (bending radius ≤5 times the wire diameter) and wear resistance (tensile strength ≥50N) to meet the frequent turning requirements of robots

Power transmission: It includes cables used for transmitting high-voltage power, which connect battery packs, motors, electronic control units and other power components of electric vehicles. These cables must be capable of withstanding high current loads while maintaining safe and efficient power transmission. Data transmission: It includes cables used for transmitting data and communication signals, which are used to monitor and control information such as battery status, motor performance, and charging status, and are crucial for the normal operation and management of vehicles. Sensor connection: Usually, various sensors are connected, such as temperature sensors, speed sensors, position sensors, etc., to monitor the vehicle's status and provide feedback to the control system. Electronic Control Unit (ECU) connection: It connects various ECUs to manage and control various systems of the vehicle, including the battery management system (BMS), motor control unit (ECU), braking system, air conditioning system, etc. High-temperature resistance and corrosion resistance: Considering that new energy vehicles may operate under high-temperature or humid conditions, the wiring harness must possess the characteristics of high-temperature resistance and corrosion resistance to ensure long-term stable performance. Modular design: To simplify manufacturing and maintenance, the wiring harnesses of new energy vehicles typically adopt a modular design, allowing each subsystem's wiring harness to be manufactured and installed independently.

Principle and Function Working principle: The start-stop/shut-off wiring harness is usually connected in parallel with a small relay on the automatic start-stop switch wiring harness, and the release of the relay is controlled by a delay circuit. When starting the vehicle, the assistant manually holds down the switch for one second and then releases it, thereby disabling the automatic start-stop function. The installation of this type of wiring harness has no direct impact on the vehicle itself. It mainly changes the working state of the automatic start-stop function through circuit control. Function implementation: After installing the start-stop and shut-off wiring harness, when the vehicle starts, the system will detect the presence of the wiring harness and control the automatic start-stop function to be turned on or off according to the preset logic. For instance, in some vehicle models, after installing the start-stop wiring harness, the automatic start-stop function will be turned off by default when the vehicle starts, thereby saving fuel and reducing emissions, while enhancing driving comfort and reducing the vibration and noise when the engine starts.   Precautions for use: Before installing and using the start-stop and shut-off wiring harness, it is recommended that car owners first understand the vehicle's user manual and warranty policy to ensure that the installation and use process will not cause damage to the vehicle or affect the warranty. After installing the start-stop and shut-off wiring harness, the car owner should regularly check the connection status and working condition of the wiring harness to ensure its normal operation. If the car owner is not familiar with the installation process or is unsure how to operate it, it is recommended to seek the help of a professional technician.
