This is the IIc I posted about a week or so ago. It has a composite video issue. Still technically does but the RGB dongle got around that issue. Seems to be working perfectly now! Just need to wash up the case and keyboard and I'll reassemble.
I'm in the same boat with a non-functioning RCA/Composite output (the stock plug) on my Apple IIc, but Plamen's IIc-to-VGA adapter which I have basically does what you did. It taps the Composite output from the 15-pin connector, which interestingly enough works perfectly!
