Okay,
It's a new day and sure enough, there was some dumbassary (on my part) afoot...
I'd like to preface this with a little tip for working on pinball machines, or anything for that matter.
Don't do it when you are tired, or more specifically, when you worked a full day and skipped dinner because you wanted to "finish it".
So now comes the solution to why I didn't have a picture...
Basically I "accidentally" allowed the jumper wire from the 5V (the one from the computer case) to slide too far forward when I crimped the molex pin down- just severing it enough to lose the connection. (I "Bobbitt'd" it! ) Yanking on it again in the morning (that's what she said...) revealed the crappy crimp.
Some sleep, a belly full of breakfast, and a "proper" crimp later...
Yesssssss! I have a nice bright picture and everything seems to be all hunky-dory, for now! (foreshadowing music)
I'm still a bit fuzzy on the whole "remote board" fix though.
If anyone has a finished pic of that baby I'd like to see how it all works.
My screen is definitely brighter and the images ARE more solid but, I'd like to get a deeper black, if that's even possible on the Ducksan.
I agree with you Turbo...
The stock RGB wiring for the original connector sucks the high hard one. Once the white inner sheath comes off, the bare wire strand that is left is quite puny. I'll probably re-do the stock brown connector with some fresh supplies and some beefier (18-20Ga range) wire, so the screws have something to actually bite on.
Thanks again Pinside for putting up with my shenanigans. (Especially Borygard!)

Thanks for the tip Lukex on the jumper wire "R4". I basically used a diode leg to solder/make the connection.
As for the update...
Here are the pics of the successful upgrade!
Well, I ditched the crappy brown connector + wires to start fresh with a new .100 Molex 10 pin connector and of course matching .100 trifurcon pins.
VGA amp board... My Ducksan needed the 5V added to the back (see page http://www.ultimarc.com/vidamp.html) to make it all work. You'll find an unused four pin connector inside of computer case that has 5V (red) as well as 12V (yellow). The red wire is your 5V and the black above/next to it is your ground...
(Don't forget to sever the trace between the two half-circles too!)
Here is the Arcade VGA amp with the 5V wire soldered to the back (running to the unused red 5V inside computer case) and colored wiring installed. (Black ground from computer case was paired with black wire (ground) from amp board.)
From top to bottom...
Red=Red, Green=Green, Blue=Blue, Orange=Vert, Black=Ground, Purple=H/V.

New .100 molex connector. You can skip adding the ground to pin 2, 4, etc... it's not necessary.
However, on the other side of the white PCB (green side) says that #9 is ground while the white side says #10 is ground. I just covered my bases and did 9+10 for ground.

New .100 molex pins. (Note the R G B H/V V GND orientation on board...)

Use a diode leg to jump "R4"...
De-solder the stock resistor on R4 and re-solder a resistor leg in it's place (see pic) for a deeper black.
(Allows brightness knob on remote board to reach a darker black.)

Adjust all old settings/controls for the new brighter picture and- Voila! All done!
(Note: You need to adjust ALL the knobs on all THREE boards to get the best picture possible.)

Much, MUCH better!
