Is that a dual pass radiator? They want more flow capability than a single pass as the have more internal restriction. You'll also likely want a highr pressure cap, I run a 22# Stant Racing lever style.
You can take a temperature reading almost anywhere in the system as long as its exposed to constant water flow (not measuring hot air) but, I've had poor luck with the between the fins probe deals. I have used a inline welded bung succesfully to look at afetr radiator return temps. I did the drill and tap the manifold crossover process to add an additional sensor for the EFI in addition to the mechanical guage.
I used a little Hayden thermostatic controller until it died from being water soaked in heavy rain and now I just use a switch with a relay and an inline fuse for the water pump and the single fan. You could add a relay and fuse for each fan off a single throw diuble pole switch if you think that kind of redundancy is needed. I have a second relay relay connected to other hot on my OEM JY Mark VIII fan which the factory used for A/C override. That one is connected to the ECU I have a DPDT switch for the fan so only one circuit can be hot at a time. The theroy was to have the ECU turn on the fan based on temp range, but I've jsut stuck with manual mode.
I know the price was right but I'm not thrilled with the drilled out flush mount 'shroud'. You would be better served by a true shroud with the appropriate spacing to the radiator core, but I'm sure you know that.
