In case anyone else searches this, I spliced into the same wire that turns on the Bose amp instead of running another wire alway to the back. I can't remember which wire it is, but there is a write-up on the Infiniti forum (check M35 forum year 2006). The only wire I ran from the front was the power wire from the battery.
