Quoted from Schwaggs:Where do the wires lead on the A and B connectors connect into the machine?
Where do the white and orange wire lead that go behind the driver board that are in the wire nut?
What I was able to get, was that on the "B" connector
bottom pin is +5 volts (red wire) & top pin is ground ( black wire ).
Quoted from zacaj:So those wires just go into the harness and you can't see what they're connecting to?
Copy the ic pinouts.
Examine the back side of board.
