I bumped the thread for you. Between this, your headunit manual and the pac module manual, you should be good to go!
Its called "need help with aftermarket headunit wiring harness"

 

I wired a single DIN Sony into the '09 I had, with the same PAC unit, I think.

 

Great! Thanks, immortal. Just what I need.

 

No problem! I know what its like. That thread recall helped me out. The speakers were easy enough, match the colors. But then all the left over wires, I was like "whaaaaah? "
that thread really helped me out. Good luck!

 

No factory amp - base stereo originally. Use ew HU pre-out to the aftermarket amp and you'll have whatever functionality the HU has.

 

This may be a little late but have you double checked the front wall of the inside of your console to make sure there isn't a usb port there?

 

Yeah. My wife's has one but mine doesn't.

 

Awesome. I think the amp is going to be the easiest part. Power, ground, remote turn on, a couple of RCAs and the speaker wires. It's all the other crap that I'm worried about. I think I will just tape all the connections to test it and then remove and solder the harnesses.

 

So I made up the harness (still a couple of wires to solder) and did a test run before install. Everything works. I was having trouble with the rear speakers. I faded back and you could barely hear them. I tried switching the RCA jacks and the rears worked but not the front. Turned out the HU was set for rear sub instead of speakers. When did that become the default?! I bypassed initial setup since I would have to do it all over again tomorrow.

So tomorrow I will mount everything.

Thanks for the help guys. I likey.

 

And I won't remember later for future questions so here's a picture.
