If you're talking about the alarm system (ATA) with the dedicated siren, as opposed to using the vehicle horn, I think you're out of luck. You're cars' wiring is COMPLETELY different from the newer models, so adding a few components is out of the question. You could up-grade your car with an after-market system though. Exactly what features do you want on your ATA? Is there something about the newer cars ATA that you prefer? The function of the ATA hasn't changed that much over the years as far as break-in protection is concerned. As far as anti-theft protection goes, MB changes these functions frequently to stay one step ahead of car thieves. Some cars shut off fuel injection, some won't crank, etc. What do you want out of your ATA?
