Do you have LoJack or is this car from a car rental fleet?
I found a black box behind my fuze box and behind my steering wheel and want to know what it is. It looks like its connected to my ignition but i could be wrong. There is a ? pin connector connected to it and that leads to another little box with a bundle of wires. and 2 wires on the top that screw into it. Here are pictures of it.
