DO NOT CUT FACTORY WIRE HARNESS     Aftermarket stereo installation? Why purchase the aftermarket wire harness? Installation is easier, no guess work with wire color codes and a Headache Saver! Factory wire colors codes are not universal. See Aftermarket Videos above. We discourage cutting the factory wire harness. This section aids in troubleshooting and determining wire color codes, phasing for speaker hook up, locating power wires for installing external devices and add-ons. Diagrams may not be applicable to Bose Audio Systems     IMPORTANT - There are two (2) yellow*, two (2) gray and two (2) brown wires in this harness. Locate the +12 volt constant wire first. Label it or splice to constant wire on aftermarket stereo first. Swapping yellow wires will cause damage to any aftermarket stereo. Check fuses if your unable to find +12 volts. 1   Gray Left Front Speaker (-) 2   Tan Left Front Speaker (+) 3   Dark Green Right Front Speaker (-) 4   Light Green Right Front Speaker (+) 5   Black Ground 6   Brown Illumination 7   Gray Dimmer 8   Blank   9   Yellow* (Green) Switched +12 volts 10   Orange Constant +12 volts 11   Light Blue Right Rear Speaker (-) 12   Dark Blue Right Rear Speaker (+) 13   Yellow Left Rear Speaker (-) 14   Brown Left Rear Speaker (+)     Wire Codes and Pin Lay Out on Back of Factory Car Stereo Note the location of the connector "Keys" in yellow.   1 Ground 2 Right Front Speaker (+) 3 Right Front Speaker (-) 4 Left Rear Speaker (-) 5 Left Rear Speaker (+) 6   7   8   9   10   11   12   13 Illumination 14 Right Rear Speaker (+) 15 Right Rear Speaker (-) 16 Left Rear Speaker (-) 17 Left Rear Speaker (+) 18   19   20   21 Dimmer 22   23 Switched +12 Volts 24 Constant +12 Volts     All wire diagrams and color codes are not 100% accurate.
