How do I add button support to an electric ice trackball?

I plan on using the electric ice's support for buttons but I'm not sure how it's supposed to be wired. I see four posts on it, L,MR, and another post (it kind of looks like a top).
I'm assuming I connect the L,M,R, to the NO of the buttons I want to use but do I daisy chain the other post to the com posts on the buttons?
RandyT:
That is correct. It's a common ground setup, just like your normal button interface.

You basically have an optiwiz, with (G)round, (L)eft, (M)iddle, (R)ight. The "G" pin is the buttons common ground.
edit: too late :)
