Wow, sounds liek somethings definitely twisted, but you knew that.
I searched the entire WWW and it looks like
http://www.the12volt.com has a wiring schematics db, but you have to be a member to access. As much as I like that site, I don't need another screen name, but you may try that.
Another idea may be to email (through user profile) MECPInstaller. He's always been helpful in the Car Audio forum.
