I’m struggled with this part and I can’t find a guide here so I made it myself.
If you want to challenge yourselves, please don’t read this guide.
1. Cut off the wire that connect to the temperature sensor.
2. Disable the vibration detector with liquid soap from the bathroom.
3. Next is box on the right. There are 2 ways you can open this
3.1 Follow Riehl’s instruction.
lower left – upper right – upper left – lower right
3.2 Follow this order to unlock achievement “Sixth Sense”.

At the last screw, turn it in OPPOSITE direction.
4. Cut the 3rd and 4th wires.

6. Last step, cut the BLUE wire.
