How To Wire Dual Electric Cooling Fans 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. 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.
How To Properly Wire Electric 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. for smaller fans, both fans can be connected to a single relay as shown above, and the proper fuse should be. 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. 1. enhanced cooling performance: dual electric fans provide improved cooling performance by ensuring better airflow through the radiator. the dual fans work together to pull air through the radiator, increasing the airflow and reducing the risk of overheating, especially during heavy use or in hot weather conditions. 2. The wiring diagram for dual cooling fans typically includes a relay, a fuse, a temperature switch, and the fans themselves. the relay is responsible for controlling the flow of power to the fans, while the fuse protects the system from electrical overloads. the temperature switch senses the temperature of the system and activates the fans when.

Custom car builder david welch walks us through the install of brothers dual electric fan conversion in this step by step guide. from the mounting to the ele. I thought it was best to dive right into the wiring diagram and figure out how to make it work with the oem fan module. after drawing out 10 different ways to wire the fans, i found the easiest way to make it work. no need for aftermarket controllers, or to have the fans on all the time. this is how to wire two electric cooling fans on a mk3.
