Alex, why worry about a shroud. A shroud is good if you are using the mechanical fan. But, with the e-fans, as long as you make sure that the fans are spaced so they cover from side to side, then you are good. The other important thing is making sure that you have atleast 3,000 cfm of air (both fans running). Under that, you risk not being able to provide enough cooling under the worst of conditions. If you have a blown Expy, then going with 4,000 or even 5,000 cfm would be recommended based on your overall power.
Everything Thermo stated pretty much the same setup I have...
This is how my setup look like
Alex, honestly, I tapped right into the fuse box to a constant 12 VDC line. I wanted to avoid possibly overloading a switch contact inside the ignition switch. Also, you will find that letting the fans run for a few seconds (15-20 normally) will help with engine survivability as you will be preventing some of the water in the motor from having to try to cool some of the extremely hot components. Besides, it gives the truck a really clean look like you never had a mechanical fan installed in the truck since there are no extra wires laying anywhere. I also hid the controllers on top of the radiator, hidden by the plastic cap for the radiator.
