2008 mazda 3 hatchback wiring diagram

i need the wiring diagram for a 2008 mazda 3 hatchback, or at least the wiring color so i can install an amp to the factory system. i did do a search before posting.thanks

did you  go to vehicle wiring at the top of this page

   you may be able to get a wiring harness from local shop ..pull your radio out and cross referance it to your oem harness..example aftermarket harness top row far left pin is say right front positive cross referance to oem harness top row far left pin is green with red stripe you know that is right front positive wire and so on....i do this sometimes when diagram is needed and not available..and then i put harness back in stock ....if all else fails use anaa battery
