I presently have HID's on my 2k1 with stock lens and I have no high beams. Since I already have the ballast, am I half way there for Bi-Xenon installment or do I need a diffrent ballast?

Cant say for sure, most different companies use different plugs going to the bulbs. Some use the standard D2R or D2S style base with plug, others use wires coming out of the bulb and then going to a small plug.

I would take the new ballast, no one is going to give you a sure answer on this test. Plus the wiring is not going to be the same regardless.
