JDM power folding mirror question

[TRUSE-R]

I just wired up my JDM mirrors and they work fine, but I have an extra green wire that is not hooked up (the one next to the blue wire for the fold/unfold for the mirrors). I was wondering if anyone has run into this? What does it (the extra green wire) connect to? Also, I notice that when my mirrors fold in, the passenger mirror folds in more than the drivers side...is this normal?
Thanks in advance.
