Where's home?
As for the diagrams, you've come to the right place. There are two documents that should do what you want:
Wiring Diagrams: On that page you will find the large 24" x 12.5" multi-page wiring diagrams. At first blush they will seem overwhelming on-screen, but if you use the pop-out icon they'll open up in a new browser page and you can zoom and scroll to your heart's content.
