Thank you for your question, Shannon! This information is provided in the Service Manual. In relation to the main power cable ( 3 wire connector ) : Red = U White = V Black = W In relation to the signal connection ( 5 wire connector) : Gray = Ground Pink = VCC Orange = W Blue = V Yellow = U
One thing to add will be to make sure the impeller/fan is not rotating due to wind while checking the resistance because it will give you an incorrect reading
