So sorry for the slow response, this is inside the cabinet of 7i77 card and a pic of the position and color of wires going to plug to encoder looking from inside. I hope this helps.

Edit: The 7i77 card position 1 is the orange wire
position 2 is the Red wire
position 3 is the Gray wire
position 4 is the Green wire
position 5 is the Violet wire
position 6 is the Black wire
position 7 is the no wire
position 8 is the mo wire

Try pic again.
