The Windstar fans are each dual speed- you'll need to power both fans on low from one relay, then both on high off the second relay-however, keep in mind you can't power low speed while high speed is activated-it'll burn out the fan windings. Most "generic" aftermarket fan relay kits are not intended to be ran on anything other than a simple single speed fan. And those Jegs relays better be STOUT if you plan to use anything OEM for an electric fan.
