2005 Ford Taurus Wiring Diagram Wiring Diagram Electrical system. note: with a c on, the cooling fan motors will run continuously. cooling fan motors will not cycle on and off with a c clutch (2884). note: an exception to this is when vehicle speed is over 61 km h (38 mph) and coolant temperature is below 100°c (212°f), and a c head pressure is below 1.71 mpa (250 psi). The two diagrams above show how to build and wire an auto relay switched 2 speed ford taurus fan. parts needed 10 guage wire for the power circuit. 18 guage wire for the control cicuit. three relays 1) high speed relay, tyco vf7 12v,70amps. 2)low speed relay and aux relay, standard bosch relays.
2005 Ford Taurus Wiring Diagrams 13798 posts · joined 2002. #4 · apr 4, 2009. here is the ford wiring. how the circuit works. the electric cooling fan operates only when the ignition switch is in run. on vehicles equipped with 3.0l and 3.8l engines, the electric cooling fan can run at high or low speed. sho vehicles use a single speed fan. The ford taurus fan wiring system consists of several key components, including the fan motor, relays, fuses, temperature sensor, and control module. the fan motor is responsible for generating airflow, while the relays and fuses act as electrical switches to control the fan’s operation. Connect battery 12v through a cb or fuse to k1's common terminal. connect k1's no terminal to k2's common terminal. connect k2's nc terminal to fan low speed, and k2's no terminal to fan high speed. if you want to monitor the fan speed, just add a resistor and led to the high and low speed of the fan. eric. This video shows the radiator cooling fan fuse and relay locations for 2000 2007 ford taurus. some of the earlier year models listed did not use the #4 circu.
