Had to disassemble a Hampton Bay ceiling fan to install a new light pull switch. Hung from a paperclip while fixing but it dropped and disconnected a number of wires. Rewired by my best guesses and now fan runs OK (but only one speed) and light works OK also. I have an extra wire from the little cubic controller (three wires) which I assume to be the speed control. I need a wiring diagram so I can fix the variable speed. Right now it's on full or off depending on the wall switch.

Testimonial: "The switch I bought was the light switch. That works fine. The switch that got into trouble is the one that controls the fa speed. It has three wires that don't color-code with anything else in the setup. It's that one which is always on at set speed now, I need wiring instructions for the little black cube that apparently controls the multi-option fan speed. Right now: wall switch on, light works )on or off with the new switch I bought but fan is on all the time and does not respond to its pull chain. Hope that helps to explain it."
