I am updating some of the outlets and switches in my garage and I need a little help with the right wiring configurations that I need to finish the job. The power is coming into a receptacle box and then feeds the switches and another outlet. Diagram is below. I would like to know in what place to the wires connect too. I can't seem to find this in any of the diagrams that I looked at. Thank you in advance

Hello, We are in a ranch house and we are remodeling the kitchen, dining room and family room. This is one big space in the back of the house with no walls separating the space. In the old dining room there was just one battery operated spoke detector. There are other battery operated smoke detectors for the bedrooms and in the hallway. What are the requirements for smoke detectors in the new space? We are adding a gas cooktop and a gas fireplace in the family room. Are we required to have CO or Smoke detectors in the family room and kitchen or what? Here is the code from Ohio for smoke detectors. Doesn't say anything about kitchens spaces.
