Thanks Finchum.
It has been a year now since the install and I have not had any problems with the setup at all.
The brain module does what its suppose to do, constantly monitoring and adjusting speed. turning the fans on and off. and I monitor the temperature on my Android tablet all the time, no issue with it at all.
and you can see in the pictures that I mounted it post radiator and fan shraud, as the flex a lite recommends.
There was a guy that did this mod to his Titan and he stated that he had an issues with the control module overheating and not working properly, and he even had it mounted in front of the radiator between the radiator and the front grill. Maybe the module has been upgrade since to a better one, he did his install 5/6 years ago. Don't know but all is well on my end.
