I just had a very quick look at the wiring diagrams that I have here, and my conclusion is that you're going to have to be more specific... My understanding (feel most free to correct me anyone), is that the VIP (vehicle intrusion protection) system works thusly: sensors are attached throughout the car - windows, door open, bonnet open etc. Then, just for fun, more wires come out that work to activate the horn, lights etc. Some, if not all of these sensors go through the ECU. Now, either the alarm is itself connected to the ECU, or the sensor wires bifurcate and go into the alarm. Some VIPS have their own ECU. Which then I tihnk begs the question: what type of alarm do you have? My cursory look (and damn i'm tired), shows a lot of wiring... and I never installed my own alarm. I guess what i'm saying is that I have the info, but there is a lot of it.
