Re: Fan Relay
you should run a fan controller running the fans will keep the engine cool all the time and its hard on the fan with that much running and at higher speeds un needed wind drag while running shortens the fans life. a relay coil is grounded and is switched on the coil side with a low amp so the high side will be attached to a good fused hot source and the other lead of the relay will go to the the fan.
here for example is a bosch relay.

87 = 30 amp pwr out, when relay energized
87a = 30 amp pwr out when relay NOT energized note: 87a almost always UNUSED
