Hello I am new to the forum and am hoping to get find information on the electrical connections to hardwire my radar detector into my 2017 Acadia SLT using the molex plug connections behind the rear view shroud. I do not have a multimeter and I am looking for the ground wire and the 12V switched wire. The wires I found on the top were green/white, purple/white, black/white and on the bottom were black/yellow, solid yellow.
