well there really isnt a diagram of how to secretly install your components.
You'll need to be creative at least with the ps2.
I molded mine into my rear arm rest. ( gotta use the slim ps2 though.)
Unless you could find a rear TL armrest because I was able to install the regular ps2 into it but, not sure if the TL armrest will fit in the accord when you close it.

As for the TV screen. Im customizing a 6.5 inch JVC widescreen into my console.
The cool part the TV is sort of detachable. Its meant as a headrest monitor but im not going to use it for that.

Once im done ill post some pics but, the armrest idea might be your best bet because i've drove myself crazy over this idea too.

good luck
