So I decided about 2 weeks ago that the next big mod for my Wolfsburg 1.8t would be the SnowPerformance Water Meth Injection Kit. I also bought the Dual Nozzle Mount Kit from Scott at USRT. He's a great guy, very very helpful! While installing the kit I took lots of pictures and decided to to a brief write up on what it took to install. Also I recieved lots of help from SAVwKO as well! Props to both!

Now... lets get started!
First thing I did was remove the battery cover, HID ballasts, and intake filter.
The next step was removing the front bumper and grill. For me there were 2 screws holding the corners of the grill, and some adhesive strip across the bottom. Theres the 4 hex screws under each wheel well, and 3 across the front under the grill. Then slide the bumper forward and remove the bulbs out of the corner markers. It looks like thiswhen youre done...
You can see in the third picture the space infront of the wheel well.. Thats where I decided to mount the pump.
Next I mounted the control box on the fender side of the battery cover. I threaded the holes on the control box and used a screw from the inside out.
With the control box mounted I moved on to pump mounting. I chose the drivers side under the frame rail. With all 4 rubber bumpers seated on the framerail I simply used an adjustable clamp to secure it around the pump. Much easier than drilling and having to get a nut on the back side (Inside the Framerail). The pump is just as secure as if I screwed it on.
Next I removed the washer fluid resovwar for modification and use with the kit. There are 2 plastic blots holding it into place. One on the top towards the fender, and one on the bottom on the framerail. Then disconnect the 2 sensors and youre good to remove it. Heres a picture with it out...
And a different angle...
With the resovwar out I drilled the appropriate size hole in the bottom in the middle of the rubber grommet. Installed the threaded hose adapter (The real name slipped my mind... sorry.) Make sure to fill the grommet with "goo" sealant. It took a little while for the goo to dry so in the meantime I installed the solenoid.
Heres a pic of the resovwar installed again.
Installing the solenoid was fairly easy. Drilled a small hole in the metal under the framerail and used some threadlock on the screw securing it up to the top.
I tucked the pressure tube under the front of the car. If you reach over the edge behind the latch mechanism you can feel where it goes under... Thats where I tucked it.
Now lets begin wiring the control box... I like to have ONE nice clean harnes so Im going to describe how I did that. First off... there are 4 colored wires coming from the control box...
RED: Ignition... 12v
GREEN: Goes to RED wire coming from the pump
I cut the yellow wire shortly after tucking it into the shielding. So now you have a GREEN and BLACK wire going down. The green wire meets up with the red wire from the pump, and also either BLACK wire from the SOLENOID.
Now you have 3 grounds left...
-Control Box GROUND
I bundled all three of them together and grounded them on the same metal that secures the solenoid.
With that done we move onto the LED inside, and Ignition 12v. I brought the wires in through the same hole in the firewall that I used to bring power to the sound system so it was fairly easy. The best way is to use a metal coat hanger with a small string on the end. Simply fish it through the hole, then use the string to tie the wire to the end of the hanger... then just pull it back. I used a wire tap to get power from the GREEN wire.
Now... as for the supplied GREEN LED... I didnt like the face that the kit comes with GREEN... Nothing else in the car is GREEN, it just looks ghetto to say the least. I decided to take a trip to Radioshack lol. For less than $4 I was set up with a new BLUE Super Bright LED and a Holder. There have also been ALOT of problems with people putting in the LED and having it not work. Heres the thing...
LEDs like the supplied one run at about 3.7 volts. When the pump turns on the GREEN wire that you tapped into is going to supply the LED with 12 volts of power... Thats about 3x the MAX power. More than enough to fry it instantly. What you need to do is get a 470ohm 1/2w resistor and wire that in before the LED. (Will update with more pics soon). My camera was having trouble so Ill try to get more pictures tomorrow lol.
I placed the LED inside next to the center consol guages, and got it all wired up. 12v on one side with the wired resistor, and the other side goes to ground!
Heres the finished product...
I am waiting to get the Passenger side intercooler pipe bung welded tomorrow mourning so I can mount the nozzle there and also in the Throttle Body. I will finish the write up tomorrow and hopefully get some logs posted up the day after! Keep an eye on this thread for updates in the next couple of days!

While waiting for the welding I also cleaned and polished my FMIC, and te piping... as well as painted the radiator supports black to make it a little harder to see behind the grill. I also got new couplers to replace the faded blue/green/brownish ones that were on there...
Polishing the NOS sprayer...
Painting the radiator supports too
All back together... Sooooo much more shiney! Love it!
If anyone has any questions feel free to ask away. [IMG]http://**********************/smile/emthup.gif[/IMG]
