How to identify alarm system?
 

When I bought the car, I knew that it had an aftermarket alarm system that had been deactivated, and in the engine bay some unknown wires are hanging loose (give no problem). I'm now thinking of restoring the system, but I need to determine what model it is. I'm guess there must be some unit hidden somewhere. System controls the door locks, and turnsignal aswell.
How can I identify what system is in?
Any help is much appreciated!

I don't think there's an alarm system Scott@La Jolla can't identify. He can probably name it by the number of strands in the ground wire. Try him at the car audio forum.
