Which Wire Harness for a 2012 non-JBL system?

I have a 2012 DC Sport with the non-JBL 6 speaker systems. Soon I'll be replacing it with a Pioneer AVH-4400BH, but am not sure what wire harness I need to buy. Can anyone point me in the right direction?

I'm also wondering if the plugs for the AUX and USB are incorporated into some proprietary harness. I guess what I'm asking is whether or not the stock radio has a standard 3.5mm AUX plug and a standard male or female USB port. If that was the case, it would be super easy to use the same wires to plug into the back of the Pioneer. Somehow, I have a feeling things will not be so easy.

 

Go to metraonline.com it will give u the parts number u need and usually u won't be able to tie into the aux plug without some additional wiring and the USB I haven't done one yet so I can't tell u if I find out how I'll post up on here bout my findings
