This is a color copy of the 1972 Service manual wiring diagram, Section BE Electrical. (For Manual transmissions)

This simple document identifies the external differences in the 280Z, 280ZX "wide" and "close" ratio transmissions. Each transmission has a basic description and photo's of what to look for on the transmission.)
Specifically for the 280Z and 280ZX models in the USA and Canada.
Explans what the Code F5W71B means.
Transmission specifications per model: 280Z, 280ZX, Coupe and 2+2. (Does not cover the Turbo model 280ZX).

This is a part list with all the main replacement components. Some components are no longer available through Nissan. The dimensions are given where possible so people can source aftermarket parts. 

A number of people refer to this document for repairing the 280Z clock.
The thread where it was originally posted is no longer available so I'm posting it here in the tech articles. This is where is should be.

No credit on my part. That goes to E. Bettio for writing the article and Monkey Man for posting it

This is an instruction on how to replace the TIU circuit board with a HEI Module. Based on the 1977 model, but it can be adapted to the later 1978 model with the square plug of the early 1976 model with dual pickup.
Comment and improvements welcome.
