I have a bath fan with a main light and night light. It is currently supplied by one piece of 12-2 from a wall switch. Since this configuration makes the night light completely worthless, I'd like to split the three devices onto separate switches.

I'm comfortable with wiring, and adding another 14-3 line and switches would be no problem if it wouldn't require tearing out, replacing, and repainting a bunch of the drywall.

I looked at Insteon controls, but it doesn't appear that there are any single modules that can control three devices. I could get three separate modules and a four-device switch, but that would around $220. Way more than I'd want to put into this project.

So the best I can come up with is to mount a couple of pull cord switches on the fan unit. The pull cords would control the fan and the main light, and the night light would be direct to the wall switch. So the wall switch would turn the night light on an off, and with the switch on I could use the pull cords to turn the main light and fan on and off.

Any suggestions for a better way to achieve what I want to do?
