Hello,
Please could you help me with the hybrid system circuit diagram?
I need to trace one route of the high voltage line.

Thank you.

Sure, there are the hybrid and engine wiring diagrams as requested, also I have included a guide to help you test the connections. The large wires are high voltage so don't mess with those unless the hybrid battery is disabled.
