Hi - I need some help with this wiring project. How would I go about wiring a third switch (Hallway switch 3 in the diagram) so that the hallway lights operate on a 4-way switch system? Thank you so much for your help!

The 4-way switch need to be connected between the travlers of the existing 3-way switches. All it does is transpose the polarity of the travlers as they go through when the 4-way switch is operated.

Like such.

travler = traveler :vs_laugh: It's the spell checker, that's my story and I'm stickin' to it!
