The answer might depend on what version board you have. Mine is V3.7 , so my answer is based on mine.
Follow these 3 steps... it should get you going.
Identifying the inputs:
The analog inputs have an internal resistor pull up to 5V. When you go to the analog inputs page you will normally see the unused inputs sitting at 5V.
Test/Identify the inputs by touching the corresponding pins to ground... the voltage will read 0V when grounded (you do this when you're online, with ECU powered up).
Now you will know which inputs work and are not used.
Wiring:
If you have sensors with 3 wires (GND, 5V, Out), you need to remove the internal resistor pull-up to 5V or your reading will be affected by it. Then you wire the output to the input.
If you have a variable resistor type sensor (1 wire) you just tie it to the input (the sensor body needs to be tied to ground).
Now if you go online with the ecu and monitor the inputs, you should be able to see the voltage change when the sensor sees a change in temperature, pressure, or whatever it is that it measures.
Input Scaling:
You will want to convert the 0-5V reading into something more meaningful (Degrees, PSI, etc) so use the built in analog scaling tool or manually enter the scale and offset parameters for each input to obtain the desired reading.
