I looked at other threads on this , but just want to be clear on the hook ups. So I have purchased a genuine Shindengen SH775 R/R and understand its connections, three yellow stator wires on left connector. Right connector , inter connection goes to battery with and inline fuse , outer connection to ground.
So anything else ? do I need to do any thing with the disconnected 5 pin connectors , green regulator , white rectifier ?
Thanks for any assistance.

That might depend on what you are installing this onto.

So you are abandoning the original regulator connector and the original rectifier connector, then? If yes then just leave them unconnected.

The other connections you mention seem correct (I haven't done it myself) according to photos I find online.

The positive output connection will go to the white wire that was originally connected to the rectifier. I personally would leave off the fuse, but having it initially will be a good idea so you don't fry anything. But once it's working, I would eliminate the fuse. You can leave it, but often fuses in that position will cause more problems than they solve. Fuses tend to have a slight drop on them and just having anything inline causes a voltage drop over time. This output line is also the line used to sense the battery voltage, so if there is a drop there, the regulator won't sense the battery voltage as accurately as possible.

The ground wire would probably be best if you connect to the battery (-) directly. Looking at the full diagram, the original ground wire for the regulator and rectifier went on a very long path before getting to the battery.

Some bikes still retained the old 3-color stator wires instead of 3-yellows.

Here's the diagram snippet I'm looking at.

Perfect thank you all. Might anyone have the full color wiring diagram for the 76 KZ900 ? I tried to download off the file base but form some reason won't allow me to download, and I am signed in ?
Thanks!
