If you have the factory 3 relay fan harness all you need from the pcm harness is the 2 fan triggers to attach to it. Very easy. I also used the existing trans cooler lines and fuel lines from the donor. Everything attaches just like it did on the donor. I just ran rubber FI hose from the sending unit to the steel line from the donor. I did have to massage the tranny lines a little.
The radiator is a monster fans hardly ever come on. Plenty of room in there for it.
