Specialized ELE WIRING, SL SYSTEM, MAIN WIRING HARNESS (MOTOR-BATTERY-HMI) One Size

This Specialized SL System Main Wiring Harness connects the motor, battery, and handlebar interface on Specialized e-bikes built around the SL drive system. It carries power and data between components, so a damaged or worn harness can cause intermittent power loss, display errors, or a bike that will not turn on. It is the correct replacement part for repairs on SL system bikes and is typically installed by a qualified mechanic, since frame routing and connector handling require care. Confirm bike model and frame size with a Specialized dealer before ordering to ensure the correct harness length. Inspect connectors for corrosion or damage during installation.
