I have an outlet and switch in same box. The box has 4 sets of wires- power source, light, and two others. The switch controls a light. When I replaced the outlet with a GFCI, everything worked expect that the switch was turning the GFCI on and off. The GFCI was wired without the load out- just line in. All the wires were pig tailed. I believe I need to identify the set of wires that goes to the light to rewire the GFCI, but am not sure how to do this.

    Upload pictures of the wires going to everything. – manassehkatz Mar 15 at 19:44
  • By chance, do any of the white wires have black tape on them? Sometimes a switch loop (that would go to a light) is marked with black tape. – JPhi1618 Mar 15 at 19:45
  • "The GFCI was wired without the load out" -- does that mean you left the warning tape on the LOAD terminals and only used LINE terminals? Where did you connect the neutral to the switch cable? – Harper Mar 15 at 19:47
  • The first time I wired it like this and ended up with the switch controlling the outlet and light: i.pinimg.com/originals/a2/87/50/… This matched how it was wired when it was just a regular outlet, not GFCI. The additional white and black wires were pig tailed. There were no taped wires to mark the switch loop. – user98335 Mar 15 at 20:45

    Can you post actual photos of the wiring? – ThreePhaseEel Mar 16 at 1:36
