'03 aurora r/s alarm keyless diagram

Can somebody please help me out? I am looking for a remote start/keyless/alarm diagram. The other diagrams I have here are extremely conflicting. I am doing this install for a friend and would like to make sure I know what I'm getting into first. I am told by other installers locally that a 2003 Oldsmobile Aurora is different than all other Auroras in the past. Any information would be greatly appreiciated. I can't find any information on the download section of the 12 volt. Thanks.

What is it that has you confused? I am not sure who told you that the 03 is different than 'all' the models before it, it is the same car from 01-03. The simplest way to do an alarm/RS in that car would be with a data module. This allows you to interface with most of the required connections between the module and the alarm. Door locks/factory arm and disarm/factory transponder bypass/door trigger/trunk release/and even window roll up on some platforms can all be done on the bench before you get into the car. Have a look at bypasskit.com's XK01. The ignition harness in your 03 Aurora uses small gauge/low amperage wires so you really should get your constant +12V from the battery.Installer, IT support, and FFL. I need less hobbies.

O.K. Plus one to you on the wiring info., but here's my problem: Do you know any DATA MODULE that is an "all in one deal" that is already preprogrammed? I'm doing this for a friend and don't have the access to download one. 

they come programmed with the software, u just have to program it to ur car, and depending on rs unit u may have 2 program the remotes
