If you unplug the VDC harness behind your ABS junction box near your brake resevior, you can brake boost. If you plan to wire up a switch, I would do it here, and just kill power to that module with the switch. This way, you can break boost, and still keep your break lights functional for the street. Your speedo is killed, but who cares.
And damn...break boosting from a roll is really really fun!

Well, I brake boosted my TT tonight.
Its too early to tell if there will be any long term problems, but for a short term solution it definately works.
No ABS/VDC/Slip lights. Full functioning ABS/VDC/Slip and full functioning brake lights.
What I need to do is completely disconnect the wire from the ECU and see how long it takes to throw a code. I can then make sure that with the addition of this module that the code isn't thrown. I drove around for about 30 minutes tonight and no lights yet.

OK, took my car to the 'track' tonight and got to test the brake boost against an '02 Z06 'Vette.
The car is absolutely amazing when brake boosting. When I dropped the pedal my car was like a rocket. I only managed to pull a 1/2 car or so on him, but it was still a good run none the less.
I drove it another 2 hours or so and still no lights. I'll hook my code scanner up tomorrow and see if any abnormalties exist.

Here is a graph I made.
You can see the RPMs fall (dark blue) as the throttle position increases (light blue). This indicates that the brakes have been applied.
Boost (pink) stays constant the entire time.

I'm not sure, I guess it depends on what kind of interest there is.
I had to make some significant hardware changes to make a 12vdc output, so I'll need to make some new circuit boards. I can't imagine more then 4-5 people wanting this though, there simply arn't many people who want to brake boost.
