Converting a 4 way to a 3 way and separate switch.

I have a 4 way circuit where I want to convert one of the boxes that we never use to a switch for some new lights that I am adding. So I know the circuit would go from 4-way to 3-way and I need input on that, but also input on using the eliminated box for a new switch. There are other switches in the box that is being converted if that makes a difference in my options to power the new switch. Thanks for any and all help.

Tell us the wiring and connections in each of the 3-way and 4-way switch boxes.

With a four way circuit..... the four way switch is always in between the two three way switches.

In the following diagram is a basic four way switch layout. If you're planning to remove the four way switch then you'd combine the two sets of wires together. If you're looking at the diagram it would be the two whites and the two blacks. Then you'd have 2) three way switches controlling the lights BUT you would not have the advantage of taking power from those two connected pairs.

If you wanted to remove one of the three way switches then the wiring would become complicated as you'd have to swap a three way switch in place of the four way one.
