I proceeded to open the SCART housing and found this:

Hot glued...
After tediously, and gently removing the glue, I checked out how they wired this up.


It looks like they daisy-chained the R, G, & B GND (5, 9, 13) pins together, connecting 'em to the RGB-Switch GND (18) and Audio GND?? (4) and Data GND??? (14)
I've never seen this kind of wiring in a SCART connector before. Most of the SCART cables I own deal with RGB, then use Comp Sync along with the Audio connections.
What is the purpose of this?
Should I eliminate this ground chain and just wire up the RGB+Comp Sync and Audio? I appreciate the advice.
