the push-type clip at the connector.
③To separate the thin red wire, insert a pin in the small hold
next to the hole and pull the wire.
: Take care when separating the wires because pulling the
wires by force may damage the socket. In addition, separate the
wires on a flat and clean surface so as to prevent scratching of
the material and the PCB.
Pull the wires while
pressing on the fixing clip.
