I just bought two "smart" dimmers to replace some older ones. We have two different ceiling fixtures. The old switches only had two terminals, and both switches were tied together on one of the terminals.
The new dimmers have "hot", "load", "neutral", and "ground". I'm pretty sure we don't have grounded anything in this house (it's old) so I can just ignore that, but I can't figure out what to do with the others. It also doesn't help that all the wires in the junction box are red.
There are a total of 3 wires in the box, two on the top (presumably one each to each ceiling fixture) and one from the bottom.
How do I connect two dimmers with a total count of 8 terminals to 3 wires, as shown below?
