TSDZ2 Light Cable Set with Speed Sensor
TSDZ2 motors can power lights from the main battery and turn them on and off from the display. The light power is in the wires to the speed sensor. This wire set includes a new speed sensor with an extra connector for tapping in the lights.
Space the spoke magnet at least 5mm from the speed sensor. Increase the space if the speedometer behaves erratically or the motor shuts off.
