Just what does the stock security system do? I've never seen anything about it. I mean what activates it and what does it do when active? Also, when i was running wires into my trunk i found this preculiar looking plug laying in my front passenger feet area its a black cable with, what looks like a RCA connector on it only it has a bigger diamter so its wider. Any thoughts?
