240z Wiring Diagram

I bought a hi resolution wiring diagram recently which I found to be incomplete. It did not show the correct fuel pump wiring circuit for my 73. Datsun added an interposing relay into the fuel pump circuit to kill the power to the fuel pump in case of an accident. Thus preventing the fuel pump from spewing fuel on to a hot engine etc. I did like the idea that it was color coded which made tracing wire circuits out a snap. Also the tach wiring did not match my car. This is the rats nest I had to contend with before I figured it out.
