Mercury blue band info needed

[jpart10]

HI
I have a 50hp 4cylinder merc blueband and i have just pulled the whole thing apart and put it back together. But i have i thing i am confused with. There are two wires that come off the coil a green one and a black one. I cant remember where the green wire connects to. Could any body tell me or could any body give a decent picture of that area?
Thanks alot

The black wire connects to the post that also has a metal band on it which runs down the coil and earths onto the engine via a coil mounting bolt.
