House was built in 2016 but the builder did some odd stuff with the wiring. Because of how it’s wired I’m very unsure how to wire this circuit with a red series dimmer.
Here’s the current circuit setup:
Panel>Two wire>Light>3 wire>light>3 wire>box1>3 wire>box2.
In the pictures below box 1 will be the old work box, box2 will be the new work
