the gen 3 (4 & 5 as well) pcm can control the electric fans, its two wires you have to pin in to the connector and build a simple relay/fuse block, lastly activate the second fan with your tuning software(or have your tuner do it).

In my application i have a turbo so all the extra room i can get between the radiator and front accessories the better.
