Now here is the complete schematic
Sorry but this is not a schematic, it is a physical layout diagram and is almost imposable to read t see what circuit you have. A schematic has proper electronic symbols and does not show the physical layout just the electrical connections.

In the schematic you can see an orange wire (Volt), how should I connect this wire?
Assuming this is the emitter of the transistor then connect it to -pol
