If you tap into the engine wiring harness to a switched (IGN ON) wire, there really aren't any that will handle the current of these fans. 20 amps needs at least 12 gauge wire. the wiring that comes with the fans is fine. just run a power wire direct from the battery post to the fans. the thermostat incorporates a relay that completes the GROUND circuit. that's how the fans turn on/off. whenever the thermostat is in the "open" position (it's an adjustable doohicky just like in your house) the circuit is not completed and the fans stay off.
Here's one example:
Here's another:
Mine looks a little different than both of these (cheaper). I think when I redo things under the hood, I'll replace it with one like the 2nd image.
