My car had a switch on the outside, that had to be turned on and off to fully shut the car off and to allow it to turn on, about 2 weeks ago I removed the switch and but a 50 fuse in it's spot, allowing me to start my car without using the switch and when I turned the car off the only electrical that would be allowed to use the battery juice, were the lights, seats and my windows, but none were left on.
