3 sets of wires coming into ceiling box.
1. White, black and blue leading to a dimmable switch for the light that attaches at the box.
2. White, Black, Red to I don't know where.
3. White, Black, Red to I don't know where.

How do I wire this at the box? Thanks.

What is 'this'? What do u want to wire to the box?

Why do you say there are too many wires? I bet there are exactly the right number.

OK, I hate to say it, but if you have two 3-wire cables in the box, and you have no idea where they go, there is no way anyone is going to be able to help you either. You are literally giving us nothing to go on.

All I can say is you need to hook it back up exactly the way it was before. And if you un-did all the splices all I can say is WHY?
