I have recently acquired a set of bi-xenon projectors. On the ballast is a 9006 socket for low beam. There is another socket on the ballast which I am not sure what it is. It is a 3 prong plug. I would think it is for the high beam solenoid. My question is how do I wire into my headlight system - I currently have 9006 low beams, and 9005 high beams. I would like the 9005 high beam bulbs to flash only when the low beam xenon is off, and to not come on at all when the xenon low beams are on and I turn on the xenon high beam. Any help with wiring this would be appreciated.

please specify brand and model of ballast

the projectors are bosche, the ballast - there is AL on it. I believe these are from a 2002+ bmw 3 series. I can take a pic of it and post it if you'd like.

I have never used a Bosch ballast/ignitor combination before, so I cant really help u with that. However, read up on the already posted Bi-Xenon wiring harness examples on this page:
http://faq.auto.light.tripod.com/headlamp-harness.html

There is a few approaches to disable halogen high beams when bi xenon solenoid is activeted. One of them could be to insert a relay switch into halogen high beam curcuit (using relay terminals 87a and 30) triggered by the same curcuit as bi xenon solenoid.
The second approach, a professional install, with no moving parts, would be using eletronic components, like switch type transistor, combined with an output transistor.

Is this the combination you have? If it is, then the picture will help you hook it up. If you actually have them attached to a plastic base, the take it off and you will see where the yellow/brown power cables go and wheere the three green/red/black go to connact to the igniter. Good luck.
