2009 nissan murano rs bypass options

A few days ago we were starting to reinstall an autostart into a brand new murano w/ intellikey.   the tech was sketchy at best.  we were goin off the 07 and up altima wiring. the plug locations were the same (pretty much) with different wire colors.  we were using a Trilogix (bypasskit.com) module for the immobilizer.   The last time i called the tech from the new Directed Canada.. i.e Autostart and Trilogix they just got a new 09 murano wiring sheet in.  my question is this.. are they the same as the altimas, or do i need to rewire totally if anyone has done them with Murano specific data.  I read an early Idatalink forum that was a nightmare on that car.. tons of problems.  check engines lights, abs, vss, 15plus codes thrown.  do to this i have not finished the install until i can proceed w/ certainty.

one of the techs has a few ingnitions and acc under hood... the other has -neg ign and stuff that are behind cluster at bcm! will both/either work and how many total +/- ign and acc are there? 

rather technical question.. any good installers with firm answers would be greatly appreciated.

thanks
