Final Update:

 

Have terminated all of the relevant blue cat5e cables that were in the databox and have identified each of them accordingly.

 

Managed to also fit in my powerline adaptor and have hooked that up to the living room with a switch for the game consoles and smart tv (no ethernet jack there unforunately).

 

And because it is finally connected via ethernet, my desktop is getting speeds very close to my current Fibre Plan (Spark 100down 20 up).

 

All in all, I'd say it's been a very productive day and once again many thanks to all that chipped in !

 

Well done! And with adding the powerline adapter to connect your consoles and TV it sounds like you're all connected up. Enjoy!
