I have a dual gang light switch box which was previously hooked up to a ceiling fan with light. The two switches controlled the fan and light separately. I recently replaced the ceiling fan with just a simple light fixture and capped off the extra hot wire. Only one switch controls the light and the other switch does nothing. I'm currently looking to replace the switch that does nothing with an led guide light. The guide light requires a white neutral wire. Can I take the wire that is currently capped off at the ceiling and attached it to the white neutral line? On the dual gang box side, I attach the hot wire to the hot connector on the guide light and take the wire which goes to the ceiling (which will be attached to the white wire) and attached to the neutral connector. Will this work?
