I realize this is an old post, but in the interest of keeping everything in the same place, here's some info about the later edition found in the S2 -

The double switch on the left has this LED layout -


The LEDs on the front are aligned like this-


You can hook up some alligator clips to a 9v battery and test the whole thing using these pins-


In that last pic, the negative stays the same, while the positive can be tapped against the other pins to light up the other various LEDs.

Rather than soldering resisters to LEDs, you can buy LEDs with resisters built in, making the whole thing a bit easier. I used these ones.

Hope this helps someone!
