Installing a PS2, need some help!

[Vandakeg]

I have a PS2 I no longer use, and want to put it in the H3. I want as clean of an install as possible, and I think I have everything I need.
Now I just need to know how I should go about setting everything up.

I have the Dual DVD Headrests (dealer option) and am planning on hooking up the PS2 to Monitor A (Driver's side).

I went out and bought a 350 watt inverter. To power the inverter, I want to tap into some sort of aux. power wire so it will turn on and off w/ the vehicle. Does anyone know where the best wire to splice into would be? I should be able to ground the inverter right to the frame, unless someone tells me thats a bad idea.

The only other problem I'm having is.. where should I mount the PS2?? I'm thinking under one of the front seats is the only option. I do not need access to the cd tray (I have a hard drive installed, and all of the games can be played off that)... but I do need access to the power button.

Any and all help would be greatly appreciated!
