new twist on ballast replacement

(From Another Thread) Re: Xenon ballast replacement on '03 B6
I figure you have already solved this issue, but for future reference, all you need to do is extract the brown wires from both connectors and swap, then do the same with the red wires. You will end up with the 4 position connector ready to plug into the 5GL ballast. To extract the terminals, use a pin to shift the retainer inside the connector to release the wire terminal. Slide the terminal out of the connector to the rear.

This is the answer that I needed. Unfortunately, now I need the 4pin harness. Anybody selling one?
