I've tried searching the forums but I can't find my answer.

I have a 2006 G35X coupe. I'm looking at buying the Nissan interface for hooking up an iPod to my stock Bose system (non-nav). Everything I read says you just hook up the cable to the sat radio harness located in the trunk. However, I took the bottom out of the trunk and poked around but couldn't find where this harness is actually located. From what I read this should be simple, so I'm not sure how much dis-assembly in the trunk is necessary. Anyone have pics?
