This looks like a great forum and I am hoping someone can help. I have power coming into a light fixture which then goes to the switch. The wall in between currently has some of the sheetrock off for some other work and I have access to the wiring in between and to the switch but not all the way up to the fixture itself. How can I add an outlet between the fixture and switch? The wire is 12-2(maybe 14-2). Is this possible without 3 wire?
