Sorry I did not show the ground wires.
So there is a 3 wire (14/3) at the 4 way Box
Black - connected to”Hot” bundle
Red and White connected to back 4 way Switch
Ground - connected to ground bundle
The 14/3 goes out the box and in to the 3 way box to the right that is located on a different wall (This is why I thought the constant hot was at this box, not realizing it was coming from the 4 way box)
Back at the 4 way box, there is a 14/2 with the ground connected to the ground bundle in the box.
Black and White wires are connected to the remaining 2 terminals on the back of the 4 way switch, goes out the box to the 3 way box to the left on a different wall.
In the 3 way box to the left the 14/2 Black and White wires run to the switch and ground to the ground bundle in the box. Another 14/2 connects to the common on the 3 way and up out the box, white wire connected to the neutral and ground connected to their respective bundles in the box.
With the power on, the light fixture has no hot wires.
The 3 way switch to the left has no hot wires. (Just the hot bundle in the box, which has no wires going to the switch)
Hope this makes sense…
