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.
Electric cooling fan relay wiring diagram.
87 red wire connects to the positive wire on the electric fan.
86 gray white wire goes to the ignition switch.
30 other red wire needs constant 12 volt power from the battery.
And if a relay fails you will still have one fan running.
A relay kit our part number ccfkrl will include everything you need to properly wire up your electric cooling fans with the exception of additional wiring needed to complete all of the circuits.
You could use one relay.
It uses a 40 amp electric relay and electric fan sensor.
85 black wire.
It shows the components of the circuit as simplified shapes and the capability and signal contacts between the devices.
The first part of the installation is to install the electric fan to your radiator and remove the mechanical fan.
The cooling fan wiring diagram below is what we ve found to be the simplest and most reliable method.
However two relays will divide the load.
