Why This Guide Is Different
Most DIY content assumes you’ll figure it out. This guide is organized into a clear sequence so you always know what to do next and why it matters.
Safety isn’t a warning at the top — it’s built into the process. You’ll shut off power correctly, verify it, document the existing wiring, and follow a method that reduces mistakes.
You get clear wiring guidance, practical checkpoints, and a finish line that includes testing and compatibility awareness — so the job is completed, not just attempted.
