Hello, I have a 1997 Ford Taurus Gl and I am trying to install an Alpine CDE-121 stereo. I ordered the Scosche stereo adapter and everything fits fine. The speaker wire harness Scosche provides doesn't seem to fit the back of my Alpine. But that's not a big deal, I can just use the alpine harness and crimp. I have been able to locate the important wires off of the factory radio harness (battery, ignition, illumination, and ground) but I can't find the 8 speaker wires on the factory harness. I have looked over as many wiring diagrams as I could find and none of the wire colors seemed to match mine. I made a diagram to better illustrate my problem. The boxes where there are ? could potentially be a speaker or something else. Please help me locate the speaker wires on the factory stereo harness!
