Thanks for your email.
The thermostat temperature is actually its opening point; the thermostat isn’t fully open until approximately 12 degrees Celsius above the opening temperature.
I would recommend that the fan switch you choose be above the fully open temperature so that you give your cooling system the chance to open up and operate as it should.
If I was to be setting up your vehicle, I would run the vehicle and use an infra red thermometer to check the exact temperature at the location of the fan switch in comparison to the thermostat operation. You will be able to tell exactly what the thermostat is doing with the thermometer. In most cases there is a temperature differentiation and you will need to compensate using a different switch.
Let me know the temperatures you come up with and then I can try to identify a switch to do the job.
Is the engine you are building going to be stock or high performance? If it is going to be a high performance engine perhaps you may want to consider a cooler thermostat.
I hope this helps.

If the radiators temperature is too much lower than the engine temp then it makes the thermostats job difficult.
Your running temperature should be above the thermostat opening temp. You shouldn't be cooling the car down back below the thermostat opening temperature whilst running and you should be running the engine temp in the 90's or where ever it makes the most power. Coolant temp affects horsepower a fair bit, don't get a dyno tune with an 87 thermostat and then put a 77 in it. You will most definitely lose power.

temp sensor in the engine and the fan operation range is 95 on and 90 off with an 87 degree thermostat

Yes, when u buy the fan it's blade is fitted as if u were gonna mount it to the front of the radiator. I have twin thermos mounted behind the rad so when I took em out of the packet I undid the clips & turned the blades over & yeah reversed the polarity so the fans spin anti clockwise
Thanks mate will try it out .

Fans start at 6 volts by being in Series - that is, one fan connects to the next one. The First control wire simply applies power to the Fans in Series.
The Second Wire uses two relays to switch the fans to running in Parallel - so full 12v each.
Here's hoping someone else can put up a diagram for you. You should be able to use the Relay assembly from an EL, AU, and some BA's for this
Hold that - Found this on Trueblueford. Ignore the add-on from the left hand side - the right hand side (ECU, three relays, out to fans) is the factory diagram
