05 maxima 880xp

hello all, new to the forum here but have been around the install scene for years.  Currently lost a job and am now installing again in the interum.  Over the years i have done mostly stock replacement work, and have had lots of experience in upholstery and design in my custom work.  Which leaves a giant hole around security.  I have only installed a few alarm systems, mostly cheap run of the mill units and now find myself wanting to install a remote start piece on my wife's maxima.  I acquired a python 880xp last week from a customer who upgraded due to  damaged remote (go figure)  and i am looking to install this unit in the maxima.  I believe that i have all the neccessary parts now after a little scavenging of  the parts bins, but have some doubts about the install.  I downloaded the directechs sheet for the car and the alarm install sheet from DEI but there is alot of grey area regarding the door locks and the remote start.  so here are my questions, and hopefully someone can help.  Does the car require the 556uw that is listed in the directechs?  is the neutral safety switch neccessary on automatic models?  Can someone explain the door triggers -/+ and door locks -/+  with any clarity?  I was hoping to install the unit over the weekend but guess that i will wait until i have it all figured out first.  Also if anyone has any ideas for the ideal place to mount the brain and the relay pack in the maxima please let me know.  thanks

thanks for all the help guys.  I will have to say that there is alot more to these things now than when i last installed one years ago.  I will probably have to pass on the dome light, as im afraid that the slow dimming light will cause some trouble.  I do like the idatalink unit idea however.  I visited their website and read up on the unit, and it seems like the way to go.  I was wondering however if the datalink feature can be used on the 880?  I dont know how that would work, as the unit does not have a datalink port on it, as far as i know anyways.  The other problem i am having is that the original remote (479p) for the 880 was damaged and no longer works.  I have since located another new 479p from a doa 881, but cant seem to get it to program.  I bench installed the 880 today, and was hoping to program the remote before attempting the install in the car, but have had no luck.  Once the power supply is turned on the unit triggers and sets the siren and i have been unbale to interrupt or program the remote to stop it.  Any Ideas?   I know, I know, i should just buy another unit and scrap this thing, but i have relatively nothing invested in it yet, except the bypass module i have yet to buy. Again thanks for the help, hopefully installing next week!
