I've just posted this on another site, (copy and paste is great!!) but I thought it might be appropriate to stick it here, if that's OK.
I've just completed an install of the HID's and took a few photo's along the way. If you are unsure about fitting them, then this may persuade you to do it....
First, remove the headlamp by removing the large silver screw at the top and push down the two retaining clips at the bottom of the unit
You can then tilt the light unit forward to gain access to the rear panel which covers the bulbs. You don't need to unplug the unit if you don't want, it's up to you. I didn't
Here's the picture with the cover removed. You remove it by gently pushing the four plastic clips away from the unit.
You then use the tool shown below to make a 21mm hole in the cover - this is so that you can thread the wires through to the ballast. Don't believe any website that says you can have HID bulbs without wiring - they'll just be normal halogen bulbs.
This shows the hole freshly drilled. Make sure it's smooth around the edges. I've put it in the corner as that's the most convenient place for the wiring to thread through.
the next photo shows the wiring through the hole and the rubber grommet in place. I always put vaseline around the rim so that moisture can't get through.
Here's the wiring poking through the other side. More vaseline.....
This can be a bit tricky - you'll have to remove the metal retaining clip for the old bulb (remove that as well!), place the HID bulb in the freshly vacates hole, and put the retaining clip back on. All this whilst you make sure the bulb doesn't touch anything or get moisture on it. The wires aren't too long so it can take a bit of time.
Place the spade terminals in the cars headlamp plug - my kit was strange in that it seemed to be reverse polarity. An hours worth of head scratching solved it (swap the wires round...)
Now plug in the wiring to the ballast. Replace the rear cover onto the headlamp unit and then put the headlamp unit back into place, in the reverse order to how ou removed it.
Here's the finished product;
Sorry if the guide's a bit basic, but it works. I did the best I could with the photo's, but they were taken on my mobile so aren't the sharpest.
