Does anyone know of a site out there on the ol' www that has a database of wiring diagrams and schematics?

I've been searching for a while to find something but I have come up completly empty. I watched some mechanic get schematics off the internet before... But I don't know if that was some site you would have to subscribe to or what.

Anyway, I posted in the T-bird section yesterday as well because Im needing the schematics for the main computer and wiring diagrams leading up to the injectors. Don't even know if they ever released them at all.

Or if there is no site that might have something like this, any words of advise will be welcome.
