The VIN should normally be used to ascertain model year, so it
should be a 2000 model as far as the FSMs are concerned. There is some overlap of model years when changes have happened, but the 00 and 01 FSMs are kind of combined with the 01 FSM being a supplement of the 00 FSM.
I'll see if I've got room to host the wiring diagrams in my google drive so you can download them.
Edit here are links to download...
