Radiator Cooling Fan Wiring Diagram 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. Learn how to properly wire single or dual electric cooling fans using a relay kit and a temperature sender. see diagrams, video and tips for high horsepower applications.
How To Wire Dual Electric Radiator Fans 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). then connect switched power (usually from your ignition switch), to the blue wires on both relays (tab 86). next, splice together both black wires from the relays (tab 85) and connect them to the thermostat. Optionally, a single high current relay could be used to control both fans. the supplied diagram below using dual relays with a single temp sensor is both the most reliable and easiest method we've found for wiring dual fans. it uses our 40 amp electric relay kit and electric fan sensor. the relay isolates the high amp load of the fan circuit. Step 3: install the electric fan relay. after wiring the electric fan to the proper power source, the next step is to install the electric fan relay. the electric fan relay is an important component that controls the operation of the electric fan. it acts as a switch, turning the fan on and off when needed.
