Although I don’t own a Nissan, I think if you were to wire it into the condensor fan, you have to know when the fan comes on.  
It might be at high temps (210+) or even when the a/c button is pressed.  
I would look into wiring it into a relay, and just purchasing a thermo sensor to activate the fans.  
Or you can wire it up all the time if you prefer.

To fit the altima fans all you have to do is trim both sides of the bracket about a mm on each side.  
When putting it in, remove your top coolant hose from the rad and it should slide straight in.
