I have a 6 disc MP3/CD in dash BOSE head unit from a 2005-2006 Pathfinder.
I am experiencing the same problem as you, looking for the amp turn on lead from the radio.
Here is a diagram of my current wiring harness in my J30 viewed looking at the back of the head unit:

Here is an exact picture of the back of my radio:

I brought this head unit to a local stereo repair shop & they checked the outputs on the back of the head unit.
Here is what I found out.
On the diagram from the first link above, "K" coming out of the head unit has no power output.
"J" coming out of the head unit has 5 volts output.
"D" coming out of the head unit is a switched 12 volts. I am pretty sure it is switched with the ignition.
I am going to see if the 5 volt lead will turn the BOSE amps on this weekend & whether or not it is switched with the head unit turning on.
I tried downloading the manual for the 2005 Pathfinder from:

But it is CORRUPT!
