Hi, I have a 2 gang box, containing 3 switches that is currently used in my bathroom. 1 switch is for 3 high hats, 1 is the fan, 1 is the shower light. I’m looking to put the fan and the shower light on a timer to avoid having the kids leave these on all day/night long.
In the 2 gang box, I have 4 lines, three of them are 2 wire and one is 3 wire (3 wire controls fan and shower light). The problem is I have no idea what the other lines are, where the power is coming from etc. I attached a picture to reflect the current wiring and the proposed wiring and am looking for help to ensure I am rewiring correctly. Any help would be greatly appreciated. Thanks in advance.
