There are two coolant temp sensors, the one near the DIS is for the EEC and provides all data necessary to turn fans on and off, adjust timing and fuel for hot or cold conditions and several other things. Don't mess with it.
The sensor/sender near the water pump provides info for your coolant temp gauge.
The diagram and instructions I e-mailed you this morning keep all the standard sensors and EEC settings and functions. For example the low speed fan will still come on when you turn the AC or Defrosters on.
You can manually override the stock settings to turn the fans on earlier, but if you screw up, and set them too high the standard settings will still work.
Generally the fan settings are about 10 degrees higher than the thermostat you selected. For example 180 degree stat would start the low speed fan at 190 and the high at 200. I like mine to run as cool as possible and have the fans set to start at 180 and 190. It's important to start the fan in low speed (too many amps to start in high), that's why the high speed is set to start 10 degrees higher.
