I want to know if I can add a GFCI combo switch from an existing light. This bathroom has no outlets. I was able to put in a regular outlet for the time being. I added wiring from the light to the outlet. I bought the GFCI combo, but am so confused if I can even use it with the existing configuration. The power is coming from the light source. Any thoughts would be appreciated. There are 3 wires, black, white and ground.

Can not be done without another wire.
Of course I'm guessing that you mean a switch/gfci combo.

So if I can pigtail a black and another white wire it should work? How does that configure for the GFCI? Do I use the switch wires that are attached to the GFCI? I just might have to fork over the dough and get an electritian. I am at my wits end. Thanks for the input, I really appreciate the quick replies guys.

Yeah, a switch, GFCI outlet. So, you mean another black and white wire, pigtailed from the light?

Just another wire.
What you need is a hot to feed the receptacle and switch, a neutral to feed the receptacle, and a wire to return power to the light when the switch is turned on.

So, pigtailing would work? Or a completely new wire connected to the light? Sorry, if I sound like a dunce. I don't give up easliy. I guess how you get the power shouldn't matter. Thank you so much for your quick reply.
