I spent another hour or so digging through the chassis harness for anything obvious and I still could not find anything. Just for clarity's sake, after checking again last night:

-black w/ white stripes = 12v when the ignition is "on"
-black w/ yellow stripes = one of them is power for the fuel pump, the other, I cannot find the end.
-black w/ pink stripe & bands = I have no idea.

Anyone at all have any input at all?! This is driving me nuts!!

The FSM is not helping me here.
