While trying to install my new mpu board in my Big House pin last night I noticed that the connector coming from the power supply had been cut off. It is only 4 wires that I assume would be called the A2 to A1 jumper. 2 of the wires are white/blue/grey and the other 2 wires are solid white. Can someone help me with the sequence of the wires as well as where can I get a new connector? I can't find the wiring sequence in my schematic. I've searched on line for a picture of the connector coming into the mpu for sequence purposes but I'm not seeing wires the same colors as mine, I'm afraid to take any chances.
