Are you wanting to split the amperage between two relays to power a single speed of the fan, or do you need to power two fan speeds?

Both relays: (pins are numbered)

86 - ground
85 - +12v from fan controller
30 - battery (tie wires together to a single fuse appropriate for the fan's draw)
87 - to fan (tie wires together to single fan wire)
