Help With 99 Gs300 Halogen To Hid Conversion

[AUGuy21]

How difficult and time consuming would it be to exchange the Halogen headlights from my 99 GS to factory HID's without using the auto-leveling? Are they plug-and-play, or would I have to get into all of the wiring harnesses and other stuff? I've heard I would have to so it is not worth doing. Any help, opinions, or directions would be appreciated.

If a factory HID exchange would not be the way to go, what aftermarket HID kits do any of you recommend?

Not Plug and play. You will have to splice a few wires. Sorry I don't have specifics on which wires but I know people who have done this. It is pretty straightforward if you are willing to cut the stock harness.
