Here is a pic in my truck.

I run the same fans with a built 400 SBC and a two core aluminum BeCool radiator. Works awesome now for over 10 years. I am using the trinary switch option with my Vintage Air A/C, and have my MSD Atomic EFI system controlling the operation of both the primary and secondary fans.
