My harbor breez ceiling fan pull chain broke inside the switch I bought another 4 wire switch I wired it up but it doesn't work I assume because of the wires. The switch is a harbor breeze switch 33905 the back has openings for 1,2,3 and L . My wires are orange yellow, purple, and black question=which goes where?

They go in the same places as they did on the original switch.
