Default 2012 Passat HID DIY Install

I contacted DistantXtremes because I heard from some of my friends they had some very high quality HID kits. I talked it over with their customer service and determined that the best kit was the XE+ Premium 35w Slim H7 Kit in a 6000K color option.
I placed my order and in 3 days they where at my door By accident I got a 35W kit and a 50W kit. They corrected this by overnighting one of each so I could choose. The difference was minor but the 35W had a much cleaner look from the front end....driving down the road they looked very similar and the 35W kits are recommended over 50W kits, less energy usage.

I went to install them without paying any attention to a real DIY but I did read the section of this DIY about the wires and color codes http://www.myturbodiesel.com/forum/48555-post18.html (Thanks TDI Brad)
Please read this whole thing prior to starting so you won't feel like this later.:banghead::banghead::banghead:
The below picture is for reference of what the back of 2012 VW Passat Headlight housing looks like:

This install was done by my friend Jasen and I documented it all. So just ignore the part where I keep saying I, because that was all him. I started by removing the headlight bulb from the driver and to my shock found this:

Yes, VW again has come up with their own unique bulb harness. I was determined to install the HIDs. I did find a set of headlight bulb adaptors from USP (Click here for the link) during my install which was too late and I didn't want to spend $24 for adaptors. I am cheap and with my buddies help and a Dremel we made it work. So in order for the bulb to fit you need to dremel out a nice big hole while retaining the front portion of the housing as seen below.


Once you have done this and saved yourself $24 now for the fun stuff. Install the new HID headlight.

When reinstalling the headlight keep in mind this notch is straight up and down.

Do that for each side.
Now onto wiring, refer to the picture above to locate the headlamp housing harness. Disconnect the harness. (I am terrible at getting these connectors off, so Jasen did that.) On either light you will notice the connector is numbered. The headlight wires are Pin 5 negative(-) and Pin 6 power (+). On both sides the negative wire is brown, but the power wires are different on each side so the driver side driver side is a yellow wire with a black strip and pass side wire is a yellow wire with a blue strip).
So you can splice, tap, or solder the wires. We soldered the wires to the ballasts.
