Yamaha Clavinova clp-320 - missing parts

I inherited this piano but it seems to be missing the cords to plug it in.

I seem to be missing 2 things:
1. The outlet cord. I found a replacement on Amazon.
2. The 2nd piece I'm having a harder time identifying - it could be the outlet for the pedals? It comes from the back of the piano and the end of it is a metal circular piece. What attaches to this??
