Did not write down how it was wired when I tool off and new switch has different colors. I have two sets of lights on my ceiling fan. It used to turn all on or 1 or the othe ron or all off. I now have blue red an dblack wire on switch. I have the 2 main wired coming out of fan (black and white) and the 4 ea black and white wires for th ethe other set of lights. What do I attaché the sw wires too?

Hard to tell but the wiring probably is;

White from the fan to white of both lights;

Black from the fan to black of the switch;
Red of the switch to black of one light and blue from the switch to the black of the other light.

If you don't like the sequence of how the light come on, reverse the red and blue.

It lights don't work like they are suppose to, rewire using black of fan to red of switch. If that doesn't work rewire using blue.

As long as you go white to white you won't hurt anything.

There is only six possible combinations. Try them all.
