For those with HID retro-kits, please enlighten me (Pun was SOO intended!)

Wiring shouldn't be an issue
As stated the wiring can handle 55W easily and then some more. I don't know exactly what the power draw is when the igniter is used but ongoing power, I think the power draw is around 35W.

Look for the 209 relay
This was done on an S4 back in August 2004, took me a while to find the photos.
In the second image you'll see the two contacts that's circled. Stick a piece of electrical tape in there to prevent the DRL from coming on automatically. You can see the tape barely in the third photo, so it's between the left most two contacts.
Just make sure when you do the wiring, that the splices you make are insulated properly. If not, you can run into a problem where it'll arc across the wire and the xenon will shut off. And probably an electrical hazard too
