Is this taken directly from the FSM? When i was wiring my motor in I noticed there were many differences between the FSM to the actual car. The only way I made any sense of it all was tracing each individual wire to the ECU.

You are correct. This is the problem with Nissan as the FSM sometimes does not line up with the actual car.

I did the best I can with the FSM, but the best way is to trace each wire to the source.
