Thanks to Heath for this tip . . .
Need service manuals but the factory ones are too expensive or the third party ones don't contain the information that you need go to:

For $20 you can download Nissan factory service manuals for a 24 hour period. They contain all the information including wiring diagrams, pin outs, exploded views and much more. Well worth the money!
