This info came from using my factory shop manual (although I find the wiring diagrams to be hard to follow) and tracing wires in my rig (1999 model year). It's also important to note that the colors given are located on the vehicle side of the front speaker connectors..... after my install I'll post a wire color comparison chart between the colors present on the Infinity speakers and those listed in this post.
Hope this helps everyone out... .
