::)on some scooters the harness is for several different scooters , on my downtown 300 I have 2 wires up front and 1 wire on the right side with nothing to hook them up to,. and on my Piaggio there is 2 wires just back of the gas tank with no where to hook them to. if your scooter runs well don't worry, or you would have to bring it to the dealer and put a diagnostic tool to check it out,
