When I had this on the bench it read the correct voltage for the acc. bat.
I am not getting motor amps , battery amps or motor temp. I did not hook-up battery temp.
I will get back at it to find my mistake(s).

Alvin,
You may want to use a DMM and verify some voltages when installed in the car. What is the voltage on the 5V regulator? What is the current draw from the LCD controller board? Should be in the 120mA range. The ACC voltage changes could be due to other loads in your car causing a voltage drop in the wiring. It only reports the voltage as it appears at Vin. Again, you may want to put a DMM in parallel. It may very well see the same thing.
Motor and battery amps are from the serial message. Is the Cougar controller set to output the message? (rtd-period=200, then save). Motor temp would be the thermistor so that should work. As a starter you could just put a 10K resistor in it's place right on the terminal block.
Keep us posted or pm me if you wish.
