How did you get the rubber housing off? I was able to splice one of the wires and get my hatch working again, but there's still a few cables that are worn out that I can't get to with the rubber thing in the way.
but you are lucky, 2009 has removable taillight,
2007, didn't, I had to splice that one!
I assume you are referring to the Center High Mounted Stop Light?
It is not model year related, it is a Rabbit vs GTi / r32 difference.
The incandescent CHMSL on the Rabbit is removable for bulb replacement.
The LED CHMSL on the mk5 GTi / r32 is glued on.
While VWOA warranty replaces a defective LED CHMSL for 10 years unlimited mileage,
that won't help on the harness fix.
