does not include the metal tabs as shown in the picture. it is unused!
the crystal port does not include the metal tabs as shown in the picture. it is the plastic housing only. it might be useful for replacing the plastic housing on a motor if it has cracked, but it is utterly useless for making a new wire (for instance and extension lead or an adaptor to use power functions motors with a powered up hub).
doesn't include the metal tabs, so you cannot use these to create a new wire - you can only use these to repair a broken housing on an existing wire.
