I have a switch that controls a plug in the wall in the living room.( turns a lamp on and off) I want to put in a light fixture in the ceiling in the center of the room. I could run a wire from the plug to the new light fixture and it would be an easy fix. But without putting lots of holes in the wire getting to the plug is impossible (outside wall insulation and three cross studs in the way). i can get at the wire from the switch to the plug in the attic space. Now my question

Can i junction the wire in the attic and connect to the white and red wire and ultimately do the same thing as ( pigtailing at plug) to the wire to control the ceiling light?

Any help would be appreciated

  • At the switch its is black and red.. – Scott Jun 1 '17 at 14:45
  • Is there a white at the switch? You'll need it, and it's required in recent construction. – Harper - Reinstate Monica Jun 1 '17 at 14:52
  • Yes there is a white at the switch and at the plug is white and red... – Scott Jun 1 '17 at 14:58

Sounds like you have modern wiring so it should be pretty straightforward. The /3 cable is delivering neutral, always-hot and switched-hot (presumably red) to the switch.

You come off the switch with /2, white to the white in the switch box, and black to the switch terminal which now has red. (if you want the receptacle to remain switched, you could pigtail the red, new black and the switch together.)

Then up to your light. You're pretty much done at that point.

If you do not want the receptacle to be switched anymore, then pull the red wire off both ends and cap it with a yellow wire nut, add tape otherwise the wire nut will fall off. Push it into the back of the box in case the next homeowner finds a use for it. Then change the receptacle to a new one. The old one had a tab broken off between hot terminals, you need that tab restored. Or you could pigtail both hot terminals if you want to. Whichever is easier.

  • Just want some clarity to make sure. the wire that goes from the switch up the wall thru the attic over the trusses then down to the plug,,, in the attic I can add a junction box and connect the pigtail... white wires and black (new) with the red and to the new light box in the ceiling to hook up the new light? – Scott Jun 1 '17 at 16:34
