Not sure where to post this. I'm trying to redo the wiring in my basement workshop and wish to add an outlet to or before what is presently a light bulb fixture. I attach a crude diagram of the wires going into the fixture. Basically there is a 12-3 cable with a white, red, black and ground into the junction and a cable to the switch and one to the next outlet, and one to the bathroom lights. I've looked at my wiring book and can not find how to convert this into an outlet into which I can plug stuff. The two wires, one white and the other black into the center of the diagram is what is connected to the light bulb fixture presently with no ground wire to it. The colorless wires are white.
Thanks,
