Found these nice vent replacements on Facebook that are supposed to be LED background, it came yesterday and I just installed them but they have two wires behind them one red and one black. I’m unsure how I would wire them up…. See pictures—they fit flawless , just confused on how to get them to work. I also only want them to come on when the door is opened—-anyone have any ideas on how to proceed on how to wire these up? Any help would be appreciated.
