Hello, If someone would help me and indicate how to connect this ceiling, 3 cables come out of the ceiling, switch 2, it is best for me to light on one switch 2 middle and on the other switch 2 side, or how it goes in turn 2 and 2, nowhere I can not find and somehow marked or numbered as to what it would be cool, if anyone can help, please, I am still mixed up with these blue and brown cables.
