Fan Plan
Fans always should have a relay.
Whatever the initiator for the turning the fans on, be it an engine mounted fan switch or ECM, the output of those should go to a relay, which allows the relay to turn the fans on.

You can buy kits with a sensor that goes into the intake (or with a probe in radiator, I prefer the intake), and a relay. It only takes about 5-15 minutes to wire it all up. If you have the dual fans, get two, with the sensors being for two different heat ranges, or get the adjustable one. They are anywhere from $20-40 a kit.

I powered it using the power from the original circuit. It's been a years or so since I put it in. Basically, get a relay, with a plug on it. the plug has different colors and lengths of wires. One goes to a sensor you put in the head, or thermostat housing. Another to the battery, one for a ground, and then you have wires going to the fan. Of course there is also a wire from a switched 12v source. It's easy, super easy. When you do it, you'll be like whooooaaaaa that's easier than thought.
