does it contain 2 wires
if so they are simply can wires that store the
radio code for standard fiat kit in the body computer
meaning you don't have to put it in every time you remove it from power
if you were to plug these onto your radio it could well do a hell of allot of damage to the car so don't
unless you know exactly what your doing you should never plug anything in
even when fitting a new radio you should check the power and earth pins are in the right place as they vary from car to car radio to radio
i mean if someone gave you a box with a mains lead sticking out of it would you plug it in just because it would fit
