Overall Structure: Integrated wiring harness with original factory standard waterproof connectors at both ends. One end connects to the air conditioning control panel, and the other end connects to the evaporator fan, pressure switch, and temperature control element. Segmented with matching rubber through-hole sleeves and wear-resistant corrugated tubing sleeves, specifically designed for vehicle sheet metal wiring. Comes with original factory clips and cable ties, ensuring wiring runs seamlessly with the original vehicle piping, requiring no modification during installation. Wire Material Advantages: Multi-strand pure copper conductive core, stable conductivity, vibration-resistant and less prone to breakage. High-temperature resistant and flame-retardant PVC insulation layer, resistant to high temperatures, oil stains, and mud corrosion from construction sites. IP65 waterproof and dustproof plugs, preventing short circuits and fan burnout due to bumps and moisture. Functional Wiring Zones: Fan speed control line, main power line, temperature control signal line, and pressure protection switch line are integrated into one unit. IV. Product Functions: The complete air conditioning circuit transmission carrier, connecting the cab air conditioning panel to all refrigeration components: Transmission 24V Power is supplied to the evaporator fan to achieve multi-level airflow adjustment. Temperature control and high-pressure protection signals are transmitted to control the cooling start/stop and prevent system ice blockage and overload. The entire control circuit of the evaporator, fan, and condenser is connected in series to ensure the complete power supply and operation of the air conditioning system. It replaces aging, damaged, burnt-out terminal, and open-circuit original vehicle wiring harnesses.
