No worries Kev...
I just thought if you have enough cable to pull below the socket you can tighten the nut up without any problem with the wires still connected.
I plan to take my car to a local MOT station before IVA and thought this would help them out if I supplied the modified socket.
I plan to have my cables connected via heat shrinkable butt connectors with the inbuilt resin to make them watertight so I could setup my lights without disconnecting them each time.
