I believe you will have to tap into the common hot wire in order to get your high beams to work. I believe the car switches the grounds in order to switch from high beams to low beams. I did a bi-function HID conversion on my car, but without ever seeing how a 99 is wired, I'll have a little trouble giving advice.
