If it wasn't for matching all those annoying color codes on the individual wires, making a new harness would be pretty darn simple. Find some kynar-insulated tinned conductor cables, and this time put in some intermediate connectors, firesleeve and high-temp heat-shrink... Could probably offer them for around $1k tested.
Maybe the most important thing will be building a test fixture that verifies correct connections, tests for shorts between conductors, etc. Would be way handy to have one that could be used for harnesses still in the car. Build one that looks like LHx and EZx brains, with a centipede harness to loop out the passenger door and plug into the individual connectors under the hood. Whole thing runs on a raspberry pi controller with a USB battery pack and a Kindle Fire tablet connected by wifi. The test/diagnostic tool would be at least as handy as a new harness. Plugging each engine-bay connector in would be a huge diagnostic step too, as you'd be forced to replace all those crumbling connectors and frayed wires just to get the thing plugged in.
Maybe do the harnesses in all gray, like the CE panel?

I was working on a master checking board that would enable me to check every connection/wire, but that is also shelved, due to time constraints.

Agreed.
That whole "Do the very best job you can possibly do, on everything you touch" is just really screwed up, these days. No one wants perfection or to have to pay for it.
"Average" has become the accepted norm.
The **** I take apart, that "passes" for well done work is a fricking joke.

What you do is always a reflection of who and what you are... When you’re not around, it will always echo your name... so make sure it stands out.

Top of the pile requires that you do things better than anybody else. I hate doing the same job twice, so I need to do it better than I can every time. Too many are willing to compromise scope for schedule or budget. Then later ask why schedule and budget at least doubled to provide for doing it better the second, third or fourth time. Cheapest is hardly ever the lowest-cost solution.
For those playing along at home, every project is a balance among scope, schedule and budget. You can't change one without affecting the others. Need it faster? Need it cheaper? Need more of "it"?

You can have it done cheap

It never ceased to amaze me how there was never time to do it right but there was always time to put it right after things were fubarred - it is a weird world we live in!

I used to tell my clients:
