More switch issues

[Etrain]

Simple backstory here, my friend is back from the Military and we took up a simple project. Or so we thought. We are taking an Xbox, and a N64 into an acoustic guitar. I need to rewire the power switch for the N64, but am stumped because of all the posts that the N64 one has. I have a three post switch (hot, neutral, ground), and a two post switch (hot, neutral). I am wondering if it possible to hook these up to the stock power switches leads, so that we can use a different switch. Please include A diagram if possible. Thanks in advance
