Could not be more grateful.

It was indeed the DB37 cable being backwards. Another local team let me borrow their DB37 cable from last (not the ribbon) and everything worked great.
I reversed the ribbon, but when tightening with the vice, I went too far and bent the metal.

When testing, the CIMs began turning with no input in a spastic fashion (jolt forward, jolt back, sporadic behavior).
So I ordered the exact cable model from last year's competition as well as replacements for the male end connector for the ribbon I wrecked.
This ribbon reversal was also a problem with two local teams. Do they pull this stuff on purpose? If so, can we make a rule that it not go against Rookie teams?
