I just got a whistler radar detector and want to hardwire it so i dont have to turn it off all the time because the stupid cigarette plug is hot all the time. There is a kit to wire it to the fuse box which will be easy, im not worried about that, but how easy is it to get the wires down the vent by the windshield? Am i gonna have to drill a hole or something?? I havent looked yet, i was just wondering if anyone had done it before and if it was easy. Thanks
