2019 impala wireless phone charger wiring help

[J king]

Hi guys. I grabbed a wireless phone charger out of a 19 impala for my hot rod. The plug has 3 wires. I can’t find a wiring schematic for it online. Anyone have access to a 19 impala schematic for this? Looked all over internet and no luck. It has purple. Black and green wires.. thanks. Jim

Found answer. Black is ground. Green is switched and purple is constant 12 v

What kind of hot rod? I wonder if I could put wireless charging into my Sierra easily.
