Step 6: Why?
Why I did this.
My wife purchased this vehicle from one of them "no credit no problem" car lots. In the industry they are called "Buy here pay here" places.
We have had the car shut off a couple times when we were in-between blessings. They promised us once we made the final payment that they would give us web access to the car so that in the event it is stolen then we could disable it ourselves and see where its at. They never did so there was no incentive to keeping it in the vehicle.
Here is a picture of the inside of the device.
There is a GSM module w/SIM card to connect to cellphone towers.
A rechargeable battery pack to power the device when the battery is removed from car.
Relay to control power to the ignition.
AT MEGA chips
Judging by the traces it looks like it hooks up via USB but i'm no expert or anything.
The system can be bypassed by jumping a wire to the two blue wires.
