I just closed on a new house a few weeks ago. The back porch does not have any lights. I can tap off a junction box in the attic, but am trying to figure a way to run the wires. The house is vinyl dutch lap siding. Underneath the siding is foam board then the 2x4 structure. I thought about pulling the siding off from the area that I am going to install the lights. I could cut a large enough square section of the foam board out to give me room to install my jbox and run my wire up to the attic. Once I run the wire, I can replace the foam board and tape the seams where I cut it, then replace the siding. The house is a single story house. Does that sound like the best plan of attack? My concern is weakening the structure by cutting and replacing the foam board, but the foam board doesn't really have any structural properties.
