Take a look at your fans, remove the very bottom plate, you should see a connector with a white and a blue wire, this is the connection for the light kit. Then as noted above, go to Lowe;s or Home depot and make sure the light unit has a MATCHING connector. Follow the instructions on the light kit to complete the install. I also agree with the previous comment regarding the RED wire. There are a couple of versions of 2 switch modules, I have seen different ones at Ace, Lowe's and Home Depot, pick the one you like. Now VERY IMPORTANT, if you do not know what you are doing STOP, and call someone who does. You will end up with a HOT wire one the switch, and the black wire (fan) to one switch, and the RED wire (light) on the other switch. I chose to have the TOP switch for the fan and the bottom switch for the fan as this is the way these are positioned on the fan unit.
Hope this helps, send me a PM if you would like to discuss further.
