How to wire new cooling fan to the existing cooling fan wiring

I know it's an old subject, but I would like to know if anyone out there has change out their old loud cooling fan for the more quiet and efficient cooling fans, especially the wiring the new fans (dual fans) into the existing wiring to have the same function? The reason why sitting in traffic is no fun here especially when the temp were hitting over a 100 degrees. The old fan only pull so much air and plus there is no where for the engine heat to escape. I am also planning to change the radiator to a racing two core radiator before the winter or before the Spring. I would like to here from someone that can provide a step by step process for wiring the new fans into the existing wiring harness Thank you.:feedback::1zhelp:

An example of a parallel circuit is below, get the picture?

Hate to tell you but no aftermarket fan out there is anywhere near as effecient as the stockers. All the TT guys who go bigger turbo run two "A/C" fans. Almost everyone who was went Flex a Lite or similar has all went back to stock fans because cooling effeciency was worse than with stockers.
