Smart car power hub

I planned to add some gauges and a dash cam to the car. These would require key-on power. I didn't have any electrical schematics for the car and I don't feel that comfortable tapping into the newer car circuits with CAN busses running everywhere, so I decided to make my own power hub. It would provide fused constant and key-on power and ground connections. I'll place it in the battery well and insulate it with a piece of cardboard.
