Choose one of the rear LED units and start running its cable through the
hole on the scooter's frame. Make sure the hole is the one which
corresponds to the guide you snapped on the previous step.
Use the small cavity on the frame to run the
cable through, and then pull the cable
through the bottom of the fork.
Repeat the previous steps for the opposite LED unit - on the opposite fork.
Do not run the whole length of the LED cable. On the LED side, leave
slack enough to allow the LED unit to be mounted on the wheel cover.
