I have an old ceiling fan and recently wanted to add a light kit. When I took the cover off there was a loose red wire inside. It looks as if it had been in a wire nut because the ends were twisted. The red wire was alongside a blue wire that came from the fan's speed control switch where the pull chain is attached. Where does that wire go to and how do I hook up a light kit wirings? Thank you for any assistance.

What make is the fan?

Don't know, it was installed before I was here. Only thing I can find on the cover is Homestead Products 037.

It's a Homestead fan. How are the speeds controlled on the fan? Is there a loose white wire as well? A picture would help.
