I want to swap out my old side mirrors for some mirrors with the LED turn indicators in them. My concern is, is my truck wired for that option? I don't think turn indicator mirrors were an option for Silverados until 2003 or so. Since my truck is a 2001 and there was no indicator mirror option that year, will I have to run wires for some aftermarket mirrors? My mirrors are power-adjustable so they do have electricy running to them, I just don't know if it will power any added blinkers or not.
