I am looking for advice on how to wire this Kanlux ceiling sensor I bought on ebay.
It has a Brown wire a Blue wire and a Red wire (UK Colours)
I made a mess of the first one so have to get the 2nd one right.

Do I leave the red wire out and just use the Brown and Blue and then use connectors joining up a light, the sensor and the power, so it is like a 3-way connection.

(the instructions weren't great) the Red wire in the instruction is marked as an 'L'
This makes Me think I need 2 Lives.
Do I connect Brown to Brown, Blue to Blue, and the get a small piece of wire and bridge the Brown to the Red so that Red becomes a Live.

OR
If you know the correct way explain it to Me. Please
