After a long discussion in another thread, was able to determine that most (if not all) of our 3-way switches are wired as follows:
  • Incoming 2-wire cable to one of the fixture boxes
  • The lights are in between the switches
  • With this setup, there is power to only one box and there are no neutral wires in either box

Thanks to recommendations from OBERKC and STUSVIEWS, for a pair of switches controlling a single light, I believe I have created a diagram of how to rewire these 3-ways when there is more than one light invovled. Here is a link:

The graphic on the left is how we are wired now. The graphic on the right shows how to rewire the fixture boxes in order to provide power and neutral to both boxes.

If OBERKC, STUSVIEWS, or someone else familiar with this circuit configuration, would confirm (or suggest corrections) to the diagram on the right, I would greatly appreciate it.

Thank You ....

You diagram is correct. Good thinking on your part

Tip: After connecting everything, ensure that both switches have power (the LEDs on both switches will be lit).

Control the lights using only the one switch connected to the load.

If all is well at this point, turn on and off the switch not connected to the load. The LEDs on the side will move up (On) and down (Off).

Link the devices making each both a controller and a responder. Either switch should control the load and both switch's LEDs will respond accordingly.
