Well the missing one as you have found is for the aux socket. Well it goes to a relay which then goes to the aux socket.
You will find that alternator spade connectors fit and are the correct size and will fit the blue plug if you file one corner down less then a MM.
Reason is most come with some insulation plastic which makes them too thick to slide into the blue connector but 30 seconds with a file cures it.
Halfords sell them in a pack of two.
To open it is easy, the front part is like on a tilt so it does not full come apart like many connectors.
