I have a 4 way circuit (3 physical toggle switches). I am use to seeing this setup with two 3-ways and a 4-way in the middle. Looking at what I have, I have a 3-way, and two 4-way switches! All 4 terminals on both 4 ways have wires. There is not a 4th switch anywhere. One of those 4-ways should be a 3-way. Would one of those wires into the 4-way be useless? Is this just a different way to wire up a 4-way? In the end, I want to remove the 4 way and just be left with 2 switches in a normal 3 way. I thought I could just remove the 4 way, connect the travelers and be left with a 3 way, but I'm not sure what to do with the second 4-way. Thanks for the help.
