When you pull off the cover over the coil, on the bikes left side, you'll notice there's a ground strap that one of the coil mounting bolts runs through, and the frame paint is ground off behind it. There's your legit ground.
The second pic should be self explan, because you can see that the ACC2 is the one that is switched on with ignition, protected by a 10a fuse. Those ACC leads have labels on them already, so that helps. Cool?
