Ah, I downloaded and read the PDF manual and the image suggests the pins go where I thought…but the wire placement is still up in the air….
I would think the colored wires would go symmetrically leftmost pins (white) on main board to leftmost pins on the expansion board. That means flipping the connector on the expansion board and to do that I need to cut off the little bump…Is that correct? Can I do damage by trying or it just won’t work if the wiring is wrong?
Thanks…
