Connect the coil (pins 85 and 86) of a DPDT automotive relay to ground, and to + of the low beam. Either one to + and ground, doesn't matter.
Cut the + wire going to the halogen high beam. Connect the beam side of the wire to NC (pin 87a) of the relay. Connect the other side of the wire that was cut going to the halogen high beam, to pin 30 of the relay.
Finally, connect the + wire from the bi-xenon relay to NO (pin 87), and the other side to ground.
That should do it. When the low beam is on the relay is engaged, switching high beam + to the bi-xenon coil. When it is off, + is switched to the halogen bulb.
