Elkay Columbus 400a light timer switch single install

[James Bobbett]

I want to install a single light in the garage so that I can switch it on when I get out of the car and the timer allows me to get to the back door before switching off. The Elkay Columbus 400a seems to fit the bill nicely but the instructions that come with it don't show a single light installation. I want to use a spare 13amp socket so have run in some twin core with the plug on it and put the back plate ready for the switch. I have also run in some twin core cable to a light fitting. Trouble is the instructions show how to wire for a corridor or staircase lighting. The switch has three connections COM, NC and NO and a adjustable timer screw in the middle.
What do I need to connect to where, I have two cable ends, so two brown and two blue, one pair from socket and one pair from light socket.

Thanks for any assistance
James
