Also, I am at 120 on the voltage threshold, and seems to be close enough to fire. If whoever posts the layout file could tell everyone what theirs is at, we would set before auto-calibrating
I ended up using just 40 pin jumper pin wire, like the image below, and stripped off 10 cables. Then I broke it up into two sets of cables (11 / 19, splitting on the center ground pair). The jumper pin ribbon saved me from having to precut the IDE cable into individual strands since they pull apart easily. I am proud of the solder job itself, but should have taken a little more time like i$ on sizing each strand if desiring perfection
