Wiring a 3 speed fan switch
So here's my problem.. I moved into a new house to find out the fan switch on my ceiling fan is broke. I don't know the maker of the fan but I think I found a similar image of the fan (see below). There's 4 wires (black, purple, yellow, and orange) I would like to know the wiring configuration into the (L,1,2,3) switch. Any help would be much appreciated. It's a 42in 4 blade brass fan. Thanks
Here's the link to the similar fan
