Caution - Electricity!

Exploration Stage: Foggy Backstreet
From: Carlos Light
Description: Kira asked me to help her with the technical part of the brainteaser her father had given her. I admire her tenacity in finding her parents. Based on her description, I made a puzzle circuit board for her pyramid, but I forgot where I left it. Could you look for it?
Completed: Yes, I was talking about this puzzle circuit board. It’s used to configure the current supply correctly. I wonder what the assembled firefly pyramid will help Kira find. Her parents? Do you think they’re in the City? I couldn’t figure out the brainteaser’s whole mechanism.
