I have a 07 ranger xlt extended cab and cannot for the life of me find the right color coding for positive and negative speaker colors. I have the rear removed and the Right Rear is: Brown/white -- Brown Blue, and the Left Rear is: Green/white -- Brown/Yellow. Any help or a point in the right direction would be greatly appretiated. I have done a search here and google but havent found any right coloring... Thanks again for any information.
