Thanks for finding that diagram but I do not think it quite matches up. My right front tweeter has violet/orange-yellow/orange wires (even though it doesn't show very well in this picture). But the most interesting thing about the diagram is that all speakers appear to be originating directly from the audio module. My new speakers consist of a woofer, a tweeter and a crossover expecting a single 2 wire input. I did not think to photograph the woofer wires although they are blurry in the background. I will ask the Crutchfield guys in the morning if it is better to use the woofer wires or the tweeter wires for the crossover input.
