Security System

I have this aftermarket anti-theft system that the previous owner put in before me... I hate it and want it out.

I have no clue what it even is, so I was hoping maybe someone could help me identify it? Maybe it has some re-sale value?

All it does is make you turn the key half way, wait for a beep, than all the way (without starting the engine) and wait for another series of beeps, than you put your foot all the way on the clutch and start up the car.

It is annoying and I was hoping there is some re sale value.... Anyone know what this is all about?

Thanks.

To avoid making a new thread, would 2003 style cobra rims fit on the 2005+ mustangs?

I wanted to get 17x10.5 on the back and 17x9 on the front... From what i read, they will fit with spacers? Maybe someone could help me out here? Much appreciated!
