Ok, the install is about 1h 30min (for me).. I mean I can see maybe doing it in 40mins, but that's only if you've been doing this sort of install over and over again. I was being overly cautious and reading and rereading the directions. I have also confirmed with a friend that works at VW, that you absolutely cannot disable ur DRL's with the VAGCOM (Passats 1998-2005).
The hardest part for me was figuring out where to locate the Ballast for the Left (drivers side) headlamp. And also getting the bulb into place with the little metal peice was kinda tricky too. Maktas have you installed this suckers yet? FYI.. since the light output is so different, make sure you re-aim ur HID's. I didn't, and I was following behind my mom a few days after the install, and she said it looked like a light show behind her, and she would get dazzled everytime I hit a dip in the road.
I followed a very easy DIY from another board.. I have it in my favorites somewhere, but as soon as i find it I will post it. I would say this is a pretty easy intall....

This is what I used:

Here's a very very simple rundown of just getting the wiring right.
Ok, so you have a Ballast with a wire coming from it, and you have the HID H7 bulb with a wire coming from it.
The ballast needs to get power so at the end of the wire coming from the ballast there is two ends (you guessed it) positive and negative contacts. Ok, picture this, if you were just to go in and replace ur ordianary bulb with another bulb u simply plug the bulb into the cars harness. The normal bulb has positive and negative terminals at the bottom. Well in this case (HID"S) wires coming from the ballast are made like the contacts on a normal bulb. So you bascially take the positive wire, slide it into the postive terminal on your cars harness and same for negative. Wrap that sucker up in electical tape and you have the power done.
Now you need to get power to your HID Blub. So you take the wire coming from the HID Bulb and plug it into the Ballast. Now you have completed the circut. Very Simple. Now of course HID kits differ, but I think this is how most kits come now-a-days.
But no matter how your's looks you just have to simply remember that A) you of course need to get power to the ballast (+) (-) into your cars harness. Then you need to get that power to your new HID bulb (Ballast to bulb).
The rest of it just involves mounting the hardware, and getting the bulb into the socket.
Look at this kit for a reference and it should become clear. Even though this kit has two wires coming from the bulb, its the same principle. Those wires have to plug into the ballast empty terminal (mine actually has two, but its wrapped up to look like one). And you can clearly see the wire coming from the ballast that needs to go into your cars harness. Some kits will just add extra harnesses just to make the install cleaner.
Here is another kit. This one is just the opposite. You can see the loose black and red wires with the contacts at the end. Well a kit like this would require you to plug that wire into the ballast and then slide those two contacts into your cars harness. Meanwhile the wire going to the blub is fixed into the ballast, so you just have to snap the connectors together in the middle bringing the blub and the ballast connection together.
See the contact at the end of the red wire in the above picture, well its made just like the contact at the bottom of this regular h7 bulb below. That's what i mean by the wire coming from the Ballast can plug right into your car existing harness. U just need to tape it up to keep the wires secure.
The wiring is very simple. JUST remember the HID's need 10,000 volts to start properly so disable ur DRL's or you will be in for some bad times
