HERE ARE MY EXCERPTS FROM MY BIG HID THREAD OVER ON CGP FOR THOSE WHO HAVE BEEN BANNED:
Ok, there seems to be a half-dozen different HID threads running right now, and I think we need to get all the information in one place...
1) Not all HID kits are created equal. Most 9007-2/9007-3 kits that come with a harness/control module do NOT need or want an upgraded halogen harness installed in the car. 9007-1 kits MAY still need a power harness to keep the ballasts happy. The control module basically gets it's power directly from the battery and uses the stock headlamp connector for control inputs. The module is designed to keep the arc burning for both the low and high modes. There appears to be a delay-off circuit that is active for a half-second during the transition from low to high mode, then it pulls in the electromagnets that move the arc tubes. Do not bypass this control module.
2) HID kits that are for 9004/9007 systems may show up at your door wired improperly. You may need to swap 2 wires in the connector to convert from 9004 to 9007 wiring.
3) Some HID arc tubes are NOT positioned properly, and will produce a very bad light pattern. Place your new HID tube next to your 9007 bulb. Be sure that the center of the arc will be at the same distance from the mounting flange as the center tungsten filament in your 9007 bulb.
If you post photos of your HID kit, I will be more than happy to assist with proper wiring. Be sure to try and contact your seller and request pinouts and wire colors for their harness, as it helps greatly.
The 9007-3 VVME/FlashPlus kit requires a lot of modifications to work properly with your car. First, remove any upgraded relay harnesses for your old 9007 halogen bulbs. Next, you will have to check your blue 9007 connector to be sure that the pinout is correct. Turns out in this kit that blue is common, and brown and white are your low and high +12 circuits. Not sure why it would be wired wrong from the manufacturer, but so be it...
This was the stock kit:
This is what I had to modify to actually make it work:
The bulbs were not designed correctly to 9007 specification either. I needed to modify the base to sit differently in the 9007 adapter ring. It needed to be moved back about 1/10th of an inch to work properly, but since the bulb retract instead of tilt, the high beam pattern is almost useless. Money would have been better spent on a 9007-1 kit, as this one appears to be for the 9003 bulb...
Measurement should be ~1.75" from the middle of the low-beam filament to the top of the flange on the base. The low beam filament is radially centered in the glass:
I took it upon myself to modify the HID body so that I could pull it back from the housing a bit after I rotated and locked it into the 9007 adapter ring.
Thus lining up the HID arc position with the 9007 tungsten position:
I will be machining some proper DelrinŽ spacers after the holidays, but for now, a zip tie and some picture frame wire will do. This is a true Richard Dean Anderson moment:
The results were astounding. The beam on the right is the original HID pattern, and my new and greatly improved pattern on the left. Now all I need to do is fix my driver's side windage adjuster.
Both sides fixed:
For those of you who will ask later, this is the 4500k kit...
My custom HID lamp adapter ring:
Just waiting for the epoxy to set up over night, and then I'll install the set screws... [&:]
Very interesting thread! I'm having trouble seeing the pics while at work, but I did view them at home before. Just didn't chim in then. I'm about to install the kit I got from the group buy... NOT bi-xenon, it is the 9007-2 type when following Brian's listing of the types.
Does anyone know how this kit from the group buy works out for this modification? Does it need the spacers or modification to line up properly? Do I need to modify the (blue?) connector at all?
There is no hope getting the high beam halogen to line up correctly, so don't lose sleep about getting that to work. Your high beams are going to be virtually useless. The main thing is to make sure that the center of the HID arc is 1.75" up from the top of the mounting flange. The only reason I am able to modify mine is because of the separate ring that first installs into the capsule, then the HID installs into the ring, because the lamp locking collar does not fit over the magnet assembly on my HID kit:
Hmmm... Found a mechanical drawing on the 9007 bulb. Not sure of it's authenticity. Why Sylvania would dimension from the back of the flange to the top of the tungsten is beyond me... Will have to take another look at repositioning my HID bulbs to fit this and see what happens...
Interesting that they call that out at 1.75"...
^^^ Nice work there.
I spent my lunch break fine tuning the pattern by moving the bulb around in the housing. This is the best I got so far. Not going to mess around with it much more until I summer when I can spend some time modding the lamps further to limit the excessive high/low stroke...
(The hot spot above the pattern is just camera glare off the white surface.)
I was using an older camera that did not have manual controls, so the images are a bit washed out unfortunately...
