I need one more circuit in my garage (to run the dust collector and the table saw at the same time). I already have a circuit with ground and GFCI outlet. I also seem to have another circuit that feeds the porch light+ PIR and then it goes into the garage to come out of the garage on the front wall to feed the garage lights as in the first picture (2 wire circuit +ground) in the figure

enter image description here Below is what I think the wiring diagram would be for the above. The interrupted brown line is the garage wall on which the lights are installed enter image description here

I would like to add a receptacle combo switch so that when I work in the middle of the day to be able to switch off the garage lights like so: enter image description here

I am not sure if this is correct and if you have seen a more professional wiring diagram I would appreciate if you can point me to it. Also I am not sure if I need any sort of box other than this: enter image description here

The wall where the cable enters the wall to feed the first outdoor light looks like this(the wires are in fact vertical with the holes at the bottom of the picture, it was rotated so you can read the cable codes) enter image description here

Here is a picture inside of the box behind the firs light I will probably have to remove the PIR that was there (dead and disconnected now). Not sure if I can replace it. Removing it might add more room for the wasps that built a nest there -I just removed that and I had to patch the hot wire, as you can see the insulation was cracked… so I put some tape there enter image description here
