My Kenwood unit arrived from Amazon ($149, $100 less than Crutchfield) yesterday. Planning to install this weekend. Can you or anybody tell me what the wire colors are for the front speakers on the stock head unit? Or where can I find it? My 4Runner's a 2004 but I'm guessing the colors are standard regardless of year. Or are the speaker wire colors an industry standard?
My quick search didn't turn up anything for 2003 or 2004 but I found some info for 2006 which is probably the same. Always test and double check before cutting or splicing wires though. Even though this is a 5th gen section I'll help you out. I don't mean to de-rail this thread.
