Designed specifically for fan speed control and power supply, this wiring harness uses a red/blue/white three-color wiring sequence to precisely distinguish the speed settings. It handles power transmission and signal control for different fan speeds (fast/medium/slow), serving as the core connection harness for three-speed adjustable fans and DC cooling fans, directly determining the fan’s speed control response speed and operational stability. Suitable for household table fans, floor fans, industrial exhaust fans, portable rechargeable fans, DC cooling fans (12V/24V), and air conditioner outdoor unit fans; supports a wide voltage range of 1.5V-24V, compatible with fan motor terminals, speed switches, and power control boards, and adaptable to common miniature terminals such as PH/XH/JST. Wiring sequence (industry-standard): Red wire: Fast speed power supply / Positive power (+) White wire: Medium speed power supply / Signal feedback Blue wire: Slow speed power supply / Speed control
