I don't have a way to host PDFs, and this is a lot of info I can't easily extract to JPEGs. PM me your e-mail and I can bundle it all up for you and maybe you know a better way to format it for on here. The fuse box info alone is a lot.
I never did find the actual fuel injector connector end views for you, but I did find the wiring schematics that give you all the wire colors and how they are wired.
Edit: Never mind. I found the injector connectors too. Not sure why, but GM decided not to include the knock sensors and injectors connectors in the Grand Prix's section for 2001, but the 2001 Impala has them.
