I've really been enjoying my new HL Kv1. It's falling apart, but I knew it would since it's cheap

Anyway, I wanted to put a Deans connector on my battery and ESC, but when I went to move the battery wire, the negative wire came off. Does anyone have a close up of the power switch and where to solder what wire? I just don't want to go to the wrong pole and mess something up. None of the diagrams I've found show the detail of the switch. Thanks!
