Alberto will drop it too. 
Booger, I have been swamped catching up from the Salt Flats run, so I will try to get the wiring directions posted. Aside from the basics of hooking up a pair of relays, the trigger wire to the stock fan is all you need. And I will get that for you.
Like I mentioned earlier, I still havent sorted out how to get the fans to kick in with the AC.

Basically having trouble see why you didnt leave surface out side of the fans open instead of blocking the air flow off and being forced into the fan openings.
Looks great though!

The fans pull air not push and the shroud helps pull air through the entire radiator as oppossed to just where the fans are if put directly on the radiator, then you would miss the corners and additional space around the fans.

You might find some of these equations useful:
http://www.nmbtech.com/html/fans/eng...ering_101.html
Also knowing the rpm of the operating fan can then allow you to create a back pressure [suction loss] graph.
At zero car speed and at various track speeds to optimize the enclosure.
Unfortunately, unlike computer board fans, large fan don't usually have a tachometer signal lead so you must measure the current pulse [divide by 4 for a 4 pole fan] and use a timer to calculate rpm.
Many of these are off the shelf choices in electronic world.
Some expensive Digital VOM have a rpm function [for measuring engine speed as the points close/open].

The low speed for the stock fans kick in when relays 1 turns on. This should turn on whenever the AC is on. Perhaps you are currently triggering off of relay 2 or 3. See attached pages... Hope it helps.
EDIT: The attached is from the service manual for a 2004 G35 coupe, but I think it should be the same, but don't know that for certain.

Sharif, I sent you a note about using your shroud with the stock fans, but it sounds like that is not worthwhile given that the stock shroud is completely sealed (didn't know that - I only have a service manual to go by since you have my car!).
Thought maybe your shroud design had some magic in it since you were seeing temp reductions even at speed. Perhaps this is due to relative low pressure zones from the pull fans, even at speed...
Thoughts?

The stock shroud is sealed, except for the area around the OEM fans..just like ours. Chris originally looked at the stock shroud, and the work involved in getting them to fit, didnt seem realistic. And we save a lot of room with the shroud we made...so not even certain the fans would clear with the stock shroud.

a nice trick for increasing airflow at speed is to add "trap" doors in the corners of the shroud that are normally closed until you can ovecome their resistance with mph.spring loaded is nice but same effect can be had with heavy rubber flapper.you might want to incorporate somthing similiar in your design so that in staights you get full flow ,yet decel and corners it automatically reverts to pulling through fans.
