Connector is M8 Black 6-pin male. The 6th pin enables the turn status indicators adjacent to the turn buttons when used with appropriate main line. Very early models may not have the center pin, in which case the pin could likely be removed from plug.
Typically required when replacement is needed from physical damage, horn or light switch mechanism failure, PCB failure or plug pin damage.
Genuine Kaabo factory spare wired for plug-and-play installation.
