12v Cooling Fan Relay Wiring Diagram 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. How to wire an electric radiator fan relay temp sensor.
Engine Cooling Fan Relay Diagram How to wire a cooling fan relay rodsshop.org get alloyworks radiators many automotive newbies often start off with an older car they want to build up. 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. 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. Step 1: find the underhood fuse or relay box. step 2: remove the fuse or relay box cover. step 3: identify the cooling fan relay. step 4: ensure the power is off. step 5: replace the cooling fan relay. step 6: match your replacement relay to the original relay. step 7:install a new automotive cooling fan relay.
