To start a Yanmar 2TNV70 motor, the following wires need to be energized:

- Black wire: This is the ground wire and must be properly connected to the ground.
- Blue wire: This wire is connected to the solenoid and needs to be energized.
- Yellow wire: This wire also connects to the solenoid and needs to be energized.

Ensure proper connections and follow safety precautions when working with electrical components.
