I'm trying to hardwire my Escort 8500 X50 with the directwire smart cord into my 03 WRX. My car doesn't have the auto-dimming mirror, though, so therefore I do not have a switched wire to tap into (I'm assuming the map lights only have power to them when the button is pressed). I was hoping to place my detector up high near the rear-view mirror. I'm aware that there's lots of threads out about radar detector wiring, placement, etc., but none of them address this issue. Suggestions anyone?
