I’ve been frustrated with the wiring diagrams available for 4-way switch replacement. Luckily I had the most common wiring for a 4 way and was able to work this out. For those of you (like me) that can read and follow directions (but hate logical diagrams) like me, here’s my diagram. This is wired and working.
Thank you for sharing. I am pretty sure this will be useful for people looking for a similar wiring.
