How To Wire Dual Electric Fans Where do the four wires of an electric fan relay go (with relay numbers)? 87 (red wire) connects to the positive wire on the electric fan. 30 (other red wire) needs constant 12 volt power from the. Each relay will control a single fan, and a 30 amp fuse is recommended for each relay connection to the battery. as you can see from the diagrams above and below, it's really a simple circuit that not only provides the proper connections to control the cooling fans, but unlike the switch under the dash method you won't ever have to worry.
How To Wire Auto Electric Cooling Fan 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. The wiring diagram of an automotive electric fan relay typically consists of four main components. firstly, there is the input power source, which is usually connected to the battery or ignition switch. secondly, there is the ground connection, which completes the circuit and allows the current to flow. First, remove your car’s stock mechanical fan and mount your electric fan onto your radiator. then, install the single relay where it is safe from excessive heat and water. exposure to these elements can compromise the functionality of your new cooling system. next, connect each of the wires as per the wiring diagram. The diagram will guide you in connecting the appropriate wires and terminals. it is crucial to follow the diagram precisely to avoid any electrical mishaps or damages. 2. disconnect power supply: prior to wiring the fan relay switch, always disconnect the power supply to avoid electrical shocks or damage to the switch.
