I might also be wrong on this but; isn' the second ground on the port actually an ECM switched ground, and not a raw chassis ground? One is black/white, the other just black.
The ECM ground would be using the internal grounding to the harness..I'm going out on a limb but if its designed for ECM ground, then it may have a different expected resistance vs a chassis ground, and going straight to ground would change that value.

I am trying to find a pin out diagram of my computer. It is the blue and greeen connector version.

Do you have any idea which color wire is the ground and which is a triggered ground? I would guess the solid one is ground and the white and black one is triggered.
