2005 smart car wiring info?

I have a 2005 Smart car, and am doing an alarm/starter in this vehicle.    The only issue i am having, is that i have to find the disarm wire, and so far having no luck finding any information on this vehicle for wiring schematics? any help would be great! thanks.

There is no information on DEI's site that lists any 2005 SmartCar. They list a couple other years and models, but none listed have a factory arm/disarm listed. If you are sure that the vehicle has an alarm, take off the driver's door panel and look at the key cylinder. The key cylinder would have a wire attached to it that goes to ground when unlocking with a key. See if you can trace that wire back into the car or tap into it right in the door.Installer, IT support, and FFL. I need less hobbies.
