Boss CS-3 repair. Pics.

Hi. I'm putting this CS-3 back together and I can't fiqure out how to connect up the jacks, specifically the output.

Where does the black wire (earth?) go. I was thinking to the other pin on the dc input. I know the purple and white wires are for the switch. I just wanted to check before I screwed it up. I have the blue dc input on the top pin, is this right?

Any advice would be awesome

Thanks
