09 370z touring w/Bose w/o navi no sound issue pioneer 8100nex

Hey guys, installing my bro's head unit in his car and no matter what we do or search for cannot find an answer for our problem. I been a mechanic since 2002 and work for Subaru so I understand the wiring diagrams and how to work on cars. I just don't understand this damn Bose audio system. Items we have bought and installed. 1. Pioneer 8100nex headunit 2. Peripheral premium output converter. isve61 (4channel for matching audio outputs.) Similar to the Pacs one. 3. Metra radio harness.70-7552 and antenna harness. 40-n112. Now after everything is wired up and we installed the radio back into the car we have 1 major and 1 minor problems. 1. No sound from the speakers, no sound at all. Very confused although there was 2 harness in back of radio and only one harness gets plugged into the harness adaptor. Leaving the 12 pin harness not connected to anything (possible reason of no sound) and 2. When hitting fm mode on radio have a no data line. Possible antenna harness blue wire wrong. From the adaptor. Not major concern but want to make sure it's right. Any help on info on getting sound would be appreciated.

Anyone have any ideas? I'm thinking of telling him to just go to an audio installer today unless it's an easy fix. If you know anything let me know.
