Both the FF instructions and the Pro Flo 4 instructions indicate it's better to control the cooling fan with the EFI computer rather than the sending unit(s). For those of you who've installed the Pro Flo, correct me if I'm wrong. The only thing I really need to do is tie the brown/yellow "Fan #1" lead on the Pro Flo harness into the dark green sending unit wire on the FF wire harness. Effectively bypassing the temp sensors on the engine or radiator. Does this sound right? The FF fuse block already has a 30amp fuse and Bosch style relay, and is already connected to the battery, ignition, and fan.
