How do you connect the susies on a lorry?

Had to look up 'susies on a lorry', as the term isn't common in the trucking industry here.... it seems to refer to the air lines and electrical cables which run from truck to trailer. The air lines, you hold up at a 90 degree angle, and bring the glad hands from the hose into contact with the glad hands on the trailer. Then you rotate counterclockwise until it secures. The electrical line is pretty straightforward - you just plug it straight in.
