Folks, which of the following two wire harnesses have a thicker wire gauge?
(I know the answer already, BTW.)

Mac 128K & SE/30 Trivia Question — A Shocking Truth

First off, thanks for replying!Well, if I believe the rumours, the 128k must have the thicker wires
With regard to what you wrote though, I've never heard any rumor saying the 128K has thicker wires in its main wiring harness. But perhaps you were just poking fun, which is perfectly OK. I did make the opening post a bit non-standard, but that was for good reason. With that said, it is not true that the 128K harness has thicker wires.
Everyone else is still free to take a shot at the question!
Bingo! 
You provided the winning answer!
And what a sad answer it is.
Yes, friends, Larry Pina was wrong when he said this...
The copper inside the SE & SE/30 Main Wiring Harness (leading from the Analog Board to the Motherboard) is in fact 22AWG — the same thickness as the Macintosh 128K Wiring Harness. This is a travesty due to the fact the SE and SE/30 have "Expansion slot" ability, which means they will draw more power in an upgraded state than a Macintosh 128K ever would.
Thankfully, @zigzagjoe mentioned here that there is a pre-crimped wire solution, so I ordered these yesterday to try out:
People with a stock SE or SE/30 will likely never care about this, but anyone with a beefed up SE/30 will.
My plan is to swap out the two +5v wires and 3 of the 5 ground wires (two are twisted, so I won't touch those), in order to boost the current handling capability.
However, that doesn't help my Micron Xceed Harness though. The upside to that is the wires Micron used are 18AWG, which is nice, but I am still getting noticeable voltage drops anyway, when I have the Xceed Grayscale kit (with MacroColor 30HR video card) and the Daystar CPU-socketed 50MHz PowerCache accelerator installed.
