I have a set of hard to find OEM Shop Manuals for Z32. These manuals were used by Nissan technicians are no longer available for purchase from the dealer.
The manuals cover all Z32 models (TT, NA and 2+2) and include exploded parts diagrams, troubleshooting procedures, required torque settings, location of wiring loom connections, colored wiring diagrams, etc. See attached link for photos:
