Help with the outputs in Wiremod!

Hi, i’m starting using wiremod, but i have a problem… i don’t know how to put outputs when i’m wiring.

i’m looking this video http://www.youtube.com/user/TakeBackTheWorld#p/u/15/QUXgmuyzZJE and I have the problem in 3:16…

Finally, my question is: How to select the output
