Routing boost guage lines.
Pop out the gromet right above the clutch pedal. Please try not to loose it. There is an alternative gromet that may work better, but I did it this way.
Snake the rubber hose through the hole. Put as much as you can out there. Then grab a flashlight and balance it on a screwdriver till you can light up the area out of the hole
Pop the hood and find the light. Use a wirehanger to guide it up to the top. Note that running the rubber hose here is more dangerous that my above mentioned alternative as I don't know what will happen if the hose breaks and dangles into some water or dirt.
Then find the vacum line off the bronzed colored round thing with a Z on it attached to the intercooler. This is another dangerous part. If you want to do stupid things like myself, you will measure about 3 inches down and then cut it. Take the t-fitting that came with the guage and splice the rubber hose into that line. Here is a picture of the end result. Oh, btw, if you want to be smart then just run out to an auto parts store or home depot to find a matching high quality line... Therefore no changes to your stock setup (doh!).
# Note that I installed it about 2.4 inches away.. you really should install it a little lower, or just buy your own hose.
# Check fittings and start up car. The boost guage should read in the negative. If it doesn't jump to 0 when you give it a little gas in neutral, then somethings wrong with the hose or the guage, or your engine.
# Secure your rubber tube as it can get damaged by the clutch or rub against the edge of the hole and get cut. I wrapped some electric tape around where it hit the hole and then "temporarily" taped it down.
