Hi I'm new to this, was hoping some one could help me out.

I brought a BMW e60 last year under the assumption it had xenon headlights however recently I had a bump and the headlight was damaged so I brought a new pair of xenon lights thinking it would be a case of plug and play. However once taking it the garage I was informed that the car originally had halogen headlights and had a aftermarket conversion kit added to make it xenon. Now here's my problem, what is the best method of connecting my xenon headlights onto the original halogen wiring? BMW have quoted me £1200 for the headlight wiring loom which is ridiculous. Can some one please advice me on the best method to get around this.

Thanks in advance for any advice
