I live overseas in Germany where I can't get anyone to install a Viper 791XV on my 02 WRX Wagon so I am gonna do it myself. What I need to know is what other parts I'll need except for the ones liste below I'll need

Battery Backup 520T- Is this all I need?
Fail Safe Starter kill- What is required for this?
Audio Sensor 506T-Is this all I need?
Hood Lock 565T-Is this all I need?
Dome light supervision

Also I've got wiring directions from other threads for a 03 and just wanted to know if they are the same as an 02 WRX.

Any help would be appreciated since I'm kinda here without any local support. There is a local viper installer but there is a little bit of a language barrier.
