Compatibility:
This write up will work for both 1g and 2g installation although will ONLY work with the GReddy turbo timer or boost controller. I used the Profec B and old turbo timer, so I'm not 100% sure on whether the other versions will work as well. You'll see I used some 2g pictures for the installation and 1g as the final product, this is because the steps and part are VERY similar.
Overview:
This installation will allow you to use the useless vent under the driver lower trim that faces your junk. It's a free modification (if you already have the vent piece) that will not only look OEM with a nice flush fitment but will also be a stealthy way to have either the turbo timer or boost controller installed in the car.
Tools Recommended:
Safety Precautions:
Like anything involving a Dremel, make sure to use eye protection to avoid getting plastic bits in your eyes. Furthermore, wear a protective mask to avoid inhaling said plastic bits. Of course, during the wiring of the parts involved, disconnect the battery first.
Steps:
To begin with make sure you have the lower driver vent in question. Also note that these steps are the same for a 1g as they are for a 2g. The vent is the same from one model to the next, only difference being in the removal and installation of the lower driver trim piece.
Once you're all prepped and ready, you need to remove the lower driver trim if you haven't done so already. This will involve removing 2 bolts (screws depending on what you see there) on the front fascia of the trim piece (which are located under the screw covers as well as two bolts (screws) under said trim on either side of it. These screws can be seen in this photo:
The blue arrows denote the screws (bolts) needing removal and the red arrow denotes the vent required for the modification in question.
Once the trim is removed, 2 screws will need to be removed to dislodge the lower vent. A simple sliding motion is then required to remove it. You will notice that the vent also has 2 screws holding the duct to the fascia, remove those as well. All screws mentioned here are shown via the red arrows in the following diagram:
Now here comes the fun part. Take the front fascia of the vent and remove the ventilation vanes. They are held in via a stub-hole combination, just pry them out gently. The vanes in question are shown here with the future look of the modification to give you an idea of what you're aiming for.
You'll notice that the front fascia fits the part perfectly. It's only in the necking region that the part will not have enough clearance to fit through. This is where you'll need to trim and cut in order to accomplish this modification. The diagram below will show you where to do such actions. Although it's important to note that trial and error will be your main focus here. It's a lengthy repetitive process of fitment testing, but it'll go by quick enough.
Use whichever bits you're most comfortable with but a selection or burring and sanding tips will work wonderfully.
The next step is only if you're as perfectionist as I am. Use different levels of sand paper to smooth down the trimming and cutting you've done for a cleaner look. It won't really matter in the end as you don't see this when it's installed, but like I said, it's a perfectionist step.
Test fit again and if you're happy with the results, wire your TT or BC to make sure everything works.
Use the same steps backwards for the re-installation of the vent/trim piece and Voila!
You've got yourself a free, stealthy and OEM looking mount for your GReddy TT or BC. Easy-peezy lemon-squeezy 
Here's what the resulting work should look like once you're finished:

Tools Recommended:
- Lower Driver Vent Trim
- Dremel (with assorted bits, use the ones you prefer working with)
- Sand Paper (500-1500 grit, for the perfectionist out there)
- GReddy Turbo Timer/Boost controller (only tested these two)
- Screwdriver
