I would like to connect the light on my ceiling fan to the switch on the wall. However I cannot work out the wiring after several attempts. I would like to continue using the pully switch for the fan. So I have one live, one negative and one neutral in my switch. I have two of each in the ceiling and obviously one set provide electricity to the ceiling fan and light, I can't work out how you connect the switch wires to the wiring on the unit. Can someone help please.
