Laguna II - How to disconnect wiring block connector from rear wing-mounted lights?

Hi all, diagnosing a short in the rear lights and having a little trouble disconnecting the wiring block connector.



Access is limited with fingers so i'd be using a tool but I don't want to force it the wrong way in case i snap something..



Does the connector lift out and away from the socket or does it slide away to the side?



Haynes manual doesn't show a picture of the connector and socket so I'm not sure how they connect.



PS I am referring to the lights on the body of the car, not the tailgate.
