I have nothing to contribute to this discussion from a technical standpoint.
But I want to comment that it's absolutely amazing to see folks with decades of experience in this sort of thing freely contributing and sharing to help the 'new guy' get it right.
This is basically 'doctorate level' harness design and construction stuff.
Both theory and practical.
Way, way, waaaaaaay beyond my skill/experience.
But the fact that Jerry, Lee & Rob are willing to help at the level they are is REALLY cool.
