found the wiring courtesy of google hosted on this very site. please note that the pins are not shown in the order they are connected on the harness, the numbers show their position on the harness. I assume you know better than to use the B+ and Ground connections labelled here, use the battery for B+ and make a ground. I used the bolt that holds the side trim down as ground once I sanded a bit around the bolt hole in the body for good contact.
the positive speaker cable is green/blue stripe and is on the bottom left of the connector at position 22. the wire next to it is the negative for the speaker. the pink wire on position 7 at the top row is the remote turn on signal.
Again, this is for the cars with the 14-speaker lexicon system only. this means signature or tech packages. base cars and ultimates have different pinouts on the harness.
