Replacement Stereo Wiring for 2003 Focus with Blaupunkt CD/MP3
Hello, I'm looking to replace my current stereo (the aforementioned Blaupunkt CD/MP3) in my 2003 Focus. There are three wiring harness(es)/plugs going from the current stereo to the car: a blue, green, and yellow one; a gray one; and a black one, which of course won't just slot in to the back of the cheap aftermarket stereo I bought. I've gone through the posts here and have seen mention that this set up requires a VW or Audi harness adaptor, but all the ones brought up only have two plugs...do I not need the third one? Any help at all would be great, thanks!
