Perfect Pepa !!!
Looks to me like three of the screened cables with outer colour of 'Blue' (2) and 'Grey' (1) have been muddled up.
1. Unplug the 2 Blues & the Grey in the second from left connector in the group of 4.
2. Plug the '2 connection Blue' into the first (left) connector in the group of 4.
3. Plug the '3 connection Blue' into the second (left) connector in the group of 4.
4. Plug the '3 connection Grey' into the second from left connector in the group of 3.
That should do it.
