So im going to be doing a new sound system in my 2006 A3 2.0t and im having a hard *** time finding a wiring harness. i have just the single din radio nothing big at the moment but im wondering what anyone had done for wiring. ill be installing an Alpine IDA-X100 head unit up front and im used to having a harness to go off the stock adapter. .... Help please i guess. this is a little aggrivating. Thanks
