How To Wire Electric Cooling Fan Automotive Start with taking both of the positive wires from the fans and connect them to the yellow wires on each relay. you will then need to run switched power (usually from your ignition switch, but modern replacement wiring harnesses usually have a fused fan relay trigger wire) to the blue wires on the relays. next, both of the black wires from the. This video shows how to easily wire an electric radiator fan circuit into any car. this fan wiring diagram includes a fan relay, a temperature switch, and a.

Electric Cooling Fan Control Wiring Diagram 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. for smaller fans, both fans can be connected to a single relay as shown above, and the proper fuse should be. 87 (red wire) connects to the positive wire on the electric fan. 30 (other red wire) needs constant 12 volt power from the battery. 86 (gray white wire) goes to the ignition switch. A dual fan relay diagram is a schematic representation of a circuit that controls two electric cooling fans in a vehicle. the diagram shows how the wiring and components are connected to ensure proper operation of the fans. it is commonly used in automotive applications to regulate the temperature of the engine and prevent overheating. Or a single relay could be used to control both fans. the cooling fan wiring diagram below is what we’ve found to be the simplest and most reliable method. it uses a 40 amp electric relay and electric fan sensor. start your wiring project by taking both of the positive wires from the fans and run them to the yellow wires on each relay (tab 87).

Yes, you can. but it is risky. the electric cooling fan setup has a high amp draw on start up, which can blow the 30 amp fuse that protects the relay and wiring. most relays have a 30 amp fuse. if this fuse blows, the cooling system goes offline, meaning the engine will overheat. a dual fan setup with a large and small fan.
