The box for the switch and gfci appeared straight forward, two units of three wires, 1 black, 1 white and 1 floor. One set for the transfer and one set for the gfci. The container for the light fixture has 2 black and 2 white wires. One black cord is unfastened, the alternative is attached to a black wire that is going into the wall and this connection is wrapped in uninsulated copper wire. I also have 2 white wires. So, i attached the black cord to the black wire at the fixture, and each white wires to the white twine on the fixture and the ground wire from the fixture to the inexperienced screw at the mounting harness.
