Does anyone know if there is an extension wire available for the sensor bar? If not, has anyone tried splicing the wire to to expand it themselves? Is it simply a posative and negative wire? I wanna move my wii farther from the TV and closer to my couch and was wondering if anyone has tried this? I have a wireless sensor bar. But I dont really like having to turn it on and off every time I play. Not to mention changing the batteries.
