Thanks, everyone. I really appreciate the help.

Bitt- I think you've explained my wiring setup really well

Trevor- that diagram is, indeed, in my manual, but there's almost zero information on how to implement it with the switches provided. Besides, one of the two switches only has three wires coming from it. A traveler, a neutral, and a ground. Clearly this second switch is designed entirely to send signals back to the primary switch and have it handle the light. I don't know if the secondary switch is able to be wired into my system.

K447- you are correct. I should have mentioned that every switch box appears to have a bundle of white wires in the back.

Currently in each box:

- bundle of white wires (not connected to switch)
- two black wires (connected to two black wires on an X10 switch)
- one red wire (connected to one blue wire on the X10 switch)
- ground (bare copper - not connected to the X10 switch, which I'd rather not be the case)

That's everything.


What I mean is that the primary switch has five wires coming out of it. They are labeled in the manual as:

- white (Neutral)
- yellow (Traveler)
- blue (Load)
- black (HOT or Load)
- green (Ground)

But none of my boxes have five wires. They all have four, which means I have an extra in the box with the secondary switch.

I've attached the manual for the 3-way dimmer if that helps.
