i in fact wouldnt use choc blocks, because any other sparkie would consider it as bungle. strange but true. totally unusual...
I like and use the wagos, and i trust them. I have see-through ones, so you can verify every single connection.
About the wire at 9 o'clock:
that was a porcelain terminal block with 4 terminals ("klemmstein").
i dont like the system very much, its just a conic shaped screw in a "u" shaped piece of metal. pretty much skill needed here to make a good connection.
i dont know why they didnt just remove the old block before adding their crap...
