I start going over everything I would need to hook it up and I realize I already have everything I need:
Xbox w/ big Hard drive & lots of games: Check
Wireless RF Controllers: Check
Wireless Network Adapter for Xbox: Check
Power inverter: Check
Space on existing power block: Check
Inline 10 A fuse: Check
Noise filter: Check
3 Position Switch (with 1 being a momentary switch): Check
So, it only took me about 2 hours but this is just my proof of concept. I still need to wire in the switch and find a better mounting place for the Xbox.
Some of the pictures are fuzzy, that's not the display, that's low light and a shaky hand:
