2010 Ford F-150 Stereo Wiring

Preparing to install an amp/sub in a 2010 f150 using factory cd player. Does anyone here have an updated wiring diagram? especially front speakers (with correct polarity) and switched 12v. Thanks

Thanks for the info. I am putting an amp/sub in (have been out of this full time for a while, doing this one as a family favor..) - I ended up pulling signal for the converter from the rear panel speakers. Where are you guys getting switched 12? I have noticed when metering at the fuse panel, many of the switched stay energized for a good bit. Am I just best to pull it from the ign. harness and be done?? Thanks again
