These three pictures show the solenoid and pressure switches. The blue lines are water lines and the red are the air lines.

Here's the same after the wiring:

It turns out that a Saab 900 windshield washer fluid reservoir fits nicely into the spare tire cavity in the trunk, with minor modifications of course. Here's are a couple of shots of the reservoir mid modification:

I chose to install water rather than nitrous for several reasons. I could have installed a wet nitrous solution, which might have even been simpler with so many bolt-on kits available. The water is cheaper, and it's not as hazardous to work with. It only needs a pump, and doesn't require the heater, pressurized tank, etc. Overall though, I chose water injection because of it's endurance. Nitrous is good for a couple of shots, but won't be there for a whole race. I've seen 1/4 mile turbo cars running +50psi using water, so I know the power is there.

More to come on this topic.
