2-Speed Cooling Fan Circuit only allows the fans to run when the engine is running (because it's powered by the fuel pump relay), but gives the driver control for water crossings or in case the temperature switches fail.
For a single-speed system: delete the hi relay, 210 switch, & resistor. For a single-fan system: derate the main 40A fuse to 20A.
