You won't find that in any manual! Your bike has had it's standard immobilser bypassed and what you have in the picture is a Chinese immobiliser emulator. See here...

What do you know about the history of the bike? What keys did you get with it?

Personally I would be a little wary of your bike's previous life. Did you do a history check on the bike? If you bought it from a dealer I'd be inclined to take it straight back and ask a few taxing questions.
