I have an Airmak AM207 ceiling fan. It has a 3 way switch with 4 wires. I am replacing the old switch and got the wires mixed up. What is the right order and color for L 1 2 3. The black is the line, grey goes to the reversing switch, purple and brown come out of the capacitor which is a Lung Chang 3 wire, 3+1.5uF300vac.
