Genuine Yadea Main Controller Wiring Harness. As the primary communication link for your vehicle, this OEM cable connects the motor controller to the dashboard, throttle, and braking systems, ensuring seamless data and power transmission.
This heavy-duty harness is engineered specifically for the Yadea KS series, featuring factory-molded connectors that provide a water-resistant, "click-lock" fit. Replacing a pinched or corroded main cable is essential for fixing intermittent power loss, error codes, or unresponsive throttle and display issues.
Installation Tip: When routing the new harness through the stem, use the old cable as a "pull wire" by taping the new one to the end of it. Ensure there is enough slack at the folding mechanism to prevent the cable from being pinched or stretched when the scooter is folded.
