Recently I became extremelly interested in OEM HIDs.
As some of you know, I got a set of brand new looking OEM HID Bi-Xenon headlight assemblies.
Here is what's inside the headlight iself:
- Leveling Motor
- D2S Xenon Bulb
- Igniter for Xenon Bulb
- City Lights
Outside the headlight:
- Ballast
In this picture of gt2437 (ORG Member, hope you don't mind
) you can see those harnesses in the corners which seal the ballast from water as well as include the relays for high-beam solenoid activation. What the solenoid does is move the shield in the projector to allow more light to pass higher up creating high-beam from the same D2S bulb. When it's not activated it blocks the light so it doesn't blind others.
Anyway, those harnesses weren't included in the sale so I have two options now.
First option would be to buy those harnesses for $115 each and send them of to PG Performance to have them modified to enable the use of manual headlight leveling switch as well as adapation from halogen equiped vehicle. The total of this would be arround $500 parts included.
Another option would be to create my own wiring harness. This would include:
- Creating relay harness with diodes, resistors, capacitors for high-beam solenoid as found in this diagram: http://img.photobucket.com/albums/v340/studout/bosch_wiring_final_v3.gif I would also have to get 3-pin wire for solenoid instead of OEM 2 pin since I'll be making my own relay harness.
- Wire three wires from ballast to the headlight assembly
- Connect three leveling motor wires to power, ground, and control (goes inside cabin to rheostat switch).
- One pin for city light. I'm using white 194 LED for this.
- Getting e46 ballast covers (e46 uses same ballasts) to protect from elements such as water
- Figuring out where to mount ballasts + covers
So far, I'm ordering the parts in for creating my own harness, but if I fail in doing so, I'll have to buy the harness and send them to Paul @ PG.
Let me know what you think and maybe give some suggestions.
