Landcruiser FZJ80 Engine Manual (1FZ-FE)

Hi All,
Do any of you guys have a genuine toyota manual for the 4500 twin cam engine. I would like to buy, borrow or copy the relevant parts to help in rebuilding my engine. If only the part number of the manual is available, perhaps l can order one from Toyota.

Also l need the connector block pin numbers and schematic for the genuine diff lock loom that is in all the 80's. I have been told that the connector block sits behind the left kick panel. I want to wire the dash lamp indicators into my air-locker circuitry.

Any help appreciated.
Cheers
BoB
