You need a screwdriver and a wrench, which you can find on the workbench in the garage.
- Hold your screwdriver and interact with the oven.
- Click on all the screws to unscrew them and remove the cover.
- Back out and put the screwdriver away; you need to do the next step empty-handed.
- Interact with the oven again and rewire it.
- Click on a red output pin to select it.
- Click on a blue input pin to connect it to the currently selected output pin.
- If you hear a sparking sound, try again - that's not the correct output pin.
- Do this for every pair of pins.
- Once all the pins are connected, back out again.
- Hold your wrench and interact with the oven again.
- Click on every input pin.
