idatalink d2d or w2w

at some point im going to be installing a viper 5701 in my parents suv and just have some questions regarding peoples experience or suggestions as to using d2d or w2w for the bypass.this is not my first r/s install probably 5th or 6th so i dont have any issues with the install itself and am familiar with the 5701 as i recently installed one for my wife in her car.

the vehicle i will be doing is a 2005 nissan xterra and i have been looking at using the idatalink ads dlsl ca2 flashed with the NI2 nissan firmware, ideally i would prefer to do d2d with the viper and understand that when it is flashed it will need to be flashed with the DBI protocol to communicate correctly with the 5701, so my main thoughts are has anyone been using the idatalink in d2d mode with dei alarms without any hiccups or problems as i know initially there were issues with communication between the two units and people opted to do w2w instead. i dont mind doing w2w if i have to but because i will have to do it outside in wonderfull canadian minus temps d2d would save me time and frostbite lol, and secondly if using d2d is the d2d cable for idatalink to dei a specific item or will a standard 4pin to 4 pin d2d cable work, i only ask as ive seen info about different cables when ive been looking around online,some places say a dbi to d2d cable others just a straightforward d2d cable, hopefully some clarification on that would help.

any advice or input is greatly appreciated
