I am remodeling my bathroom and am having trouble with the wiring of the switches. Existing wiring controlled an fan switch, separate switch for the light, a switch for vanity light and an outlet. I want to eliminate the outlet so need to wire the three switches separely in a 3 gang box. The wiring coming in is: (2) 2-wire lines (one hot coming in) and a 3-wire line. Can you show me the correct way to wire this and a diagram as well?
