Glad I’m not the only 2020 with no plug. It is gone. I tapped into the wires going to the cup holder lights. Don’t remember colors but used the 2 outside wires on the plug. Used a test light to find power and ground. I cut, soldered and put heat shrink on mine. Here are a few pics. Only complaint is my P is not as bright the rest of them.

How about a shot with it installed and showing the lights?
