I drive an 03 base Z and just switched to the newer bi-xenon headlights. My first question: Is there any wiring modification I needed to do? When I received the lights, it only had one D2S bulb (projector light). So I decided to install the lights now and place an order for new D2S bulbs. Once installed I tested the headlight that had all working bulbs, and all lights worked except for the side LED's. Not too concerned for the LED's. New bulbs came in and installed. Projector lights are now not working. Installed the old bulb and that is not working now. Can someone point me in the right direction to get my projectors working and maybe my LED's.

From my knowledge, which isn't much on the scenario, you have to either change your harness on your car to adapt to the 06+ harness or change the harness on the light to work with your base harness on the car. Most guys I've spoke to have paid a shop to do this for them. Everything then will work correctly. Hope this helps.
