I think the fan already has a relay built in along with a thermostat switch etc. You just need to run a 14 ga wire from the starter relay post with a 20 or 30 amp fuse or fusable link mounted near the starter relay (like all the other power wires leading out of there) The fan was listed to pull 14 amps, so don't go too high or there won't be any overload protection.
