This means the white is the power lead . The other two are winding leads. They will go on two of the pins on the 4 pin side of the 9 pin connector. Do the same for the other three wires. You should now have the two power leads figured out and the four wires for the 4 pin side of the 9 pin connector.
Hard part is over now.
Put the meter away, return it to the store, give it back to whoever you borrowed it from. Now if you picked the wrong A or B it does not matter. Any two pins will do just fine. I made a 9 pin connector with 6 wires coming from it that are about a foot long. 2 wires come from the 5 pin side and 4 come from the 4 pin side.
