I'm trying to install a dimmer switch (single pole) in a 4 gang box. In the current set up, I have two black wires attached to the SAME screw (one of those wires is from the back of the box, while the other wire is coming from the light switch directly beside it (it seems that all the switches have a black wire that is looped from the one beside it).
In addition to the 2 black wires I have an orange wire going directly into the switch, which I have now learned I need to use the end of an extremely small screwdriver to press into the hole to release it. I'm not sure what to do with the orange wire.
The box is metal, and there's a copper ground wire screwed to the back of the box. The dimmer switch I want to install has 2 black wires and one green wire. I was going to cap one black wire from the dimmer to one of the blacks from the switch, repeat this step with the other black wire, then take the green wire from the new dimmer and attach it to the green screw. Is that right? and if so what do I do with the orange wire?
