Mercury

How can i find my speaker wires in my 97 mercury tracer? or what color are the wires for each speaker, i really want to hook up a different radio and i need to find out what wires go to what speaker.

I would advise purchasing a wire harness adapter to fit your vehicle. http://www.sonicelectronix.com/item_1654.html the only time you should ever have to decode factory wire colors is if anybody else foolishly cut off the factory plugs before you could stop them.
