I'm trying to replace this regular light switch with a dimmer. After I open the cover, there are 2 groups of wires from the wall. I don't know why the white wires are not used, but this is the original wiring.
Left Group
- 2 white (not used)
- 1 copper for ground (connected to right group ground)
- 2 black
- letter B in the pic, plugged in to the bottom of switch
- letter C in the pic, screwed to the bottom of the switch Right Group
- 1 white (not used)
- 1 copper for ground (connected to left group ground)
- 1 black, letter A in the pic, plugged in to the top of switch
Now my question is how do I connect to the dimmer below? I know the green wire goes to the ground copper, and the red with a sticker should not be used since I'm not doing a 3-way. Which one should I connect the black and red with?
My educated guess is:
- connect A with dimmer red wire
- connect B and C with dimmer black wire
- connect ground copper with dimmer green wire
Does that sound right?
