I finally got a Kenwood DDX470 and installed in my 2007 6.0 and can actually use my iPod and phone over the system like the rest of these modern day folks.
Question is: I ordered a rear camera to add on from Amazon and want to attached the reverse wire that is available on the headunit so that it will kick on when in reverse and need to know where reverse wire and color to attach is?
Thanks in advance.

 

Bueller, anyone, Bueller?

 

On my 2003, I tapped the black/pink under the sill plate on the driver's side. Easy to access and run the wire up the kick panel and over to the head unit.
