Do you need a relay kit for dual cooling fans?
Wiring Dual Cooling Fans With dual cooling fans, there are two methods for wiring up the relay kit. This is based on the draw from the fans, if the fans are larger and draw more than 15 amps each, it’s recommended to install a second relay kit as shown below.
What kind of Fuse do you need for a fan relay?
For a second relay, both gray wires can be connected to the temperature sender, and both orange wires can be connected to your 12 volt ignition source. Each relay will control a single fan, and a 30 amp fuse is recommended for each relay connection to the battery.
