So in a Golf State and maybe some regular Golfs the Xenon Led retrofit wont work without major surgery:
Here is the connector for the regular xenon:

HEre is the one for Xenon LEds

as you can see the pins are different, they can be pulgged and they will work no dash light or problems but the LEDS WONT work.
The led version is a lot more complicated.
Also just for refecence pins 10 and 7 give 12 V to the parking lights but they wont fire up the leds.
If anyone has the led assignments for the connectors it will be greatly appreciated.
Still working on a "fix" for older version ...
